文章根据传智播客人事管理系系统OA整理,感谢传智播客。

1、新建JavaWeb项目,并修改字符编码。

在项目上右击选择最后一项,修改为UTF-8
1.1添加Junit4,右击项目选择Build path
打开,
 
 
添加以下jar包,写配置文件
2、添加struts2环境。
2.1添加过jar包之后,拷贝配置文件
2.2在web.xml中加入struts2最核心的过滤器
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  3. <display-name>SSH-1</display-name>
  4. <!--Struts2过滤器 -->
  5. <filter>
  6. <!--过滤器名称 -->
  7. <filter-name>struts2</filter-name>
  8. <!--过滤器类 -->
  9. <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  10. </filter>
  11. <!--Struts2过滤器映射 -->
  12. <filter-mapping>
  13. <!--过滤器名称 -->
  14. <filter-name>struts2</filter-name>
  15. <!--过滤器映射 -->
  16. <url-pattern>/*</url-pattern>
  17. </filter-mapping>
  18. <welcome-file-list>
  19. <welcome-file>index.jsp</welcome-file>
  20. </welcome-file-list>
  21. </web-app>
修改struts2的配置文件为
  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE struts PUBLIC
  3. "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
  4. "http://struts.apache.org/dtds/struts-2.3.dtd">
  5. <struts>
  6. <!-- 更改struts默认的主题 -->
  7. <constant name="struts.ui.theme" value="simple"/>
  8. <!-- 配置为开发模式 ,好处是修改过之后立即生效-->
  9. <constant name="struts.devMode" value="true"></constant>
  10. <!--声明包 -->
  11. <package name="pm" namespace="/" extends="json-default">
  12. <action name="product_*" class="com.atfuture.PM.action.ProductAction" method="{1}">
  13. <result name="list">/WEB-INF/jsp/product/product_list.jsp</result>
  14. <result name="success" type="redirect">/product_list</result>
  15. <result name="input">/WEB-INF/jsp/product/product_input.jsp</result>
  16. <result name="productStockAll">/WEB-INF/jsp/product/product_stock.jsp</result>
  17. <result name="cg_input">/WEB-INF/jsp/product/product_input.jsp</result>
  18. <result name="fintByCategory">/WEB-INF/jsp/product/product_cg_list.jsp</result>
  19. <result name="addinput">/WEB-INF/jsp/product/product_addinput.jsp</result>
  20. <result name="stockQuerySomeSuccess">/WEB-INF/jsp/product/someProduct.jsp</result>
  21. </action>
  22. </package>
  23. </struts>
3、添加hibernate环境
jar包,配置文件,hibernate.hbm.xml 映射文件和    hibernate.cfg.xml主文件
 
 这个必须加,不加报错。
c3p0数据源
 3.1添加过jar包后,拷贝配置文件和映射文件
 
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  3. "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
  4. <hibernate-configuration>
  5. <session-factory>
  6. <!-- 1.数据库连接信息 <property name="connection.url">jdbc:mysql:///itcastoa0720</property>
  7. <property name="connection.driver_class">com.jdbc.mysql.Driver</property>
  8. <property name="connection.username">root</property> <property name="connection.password"></property> -->
  9. <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
  10. <!-- 2.其他配置 -->
  11. <property name="hbm2ddl.auto">update</property>
  12. <!-- 3.映射文件 -->
  13. <property name="show_sql">true</property>
  14. <property name="format_sql">true</property>
  15. <!-- 测试 -->
  16. <!-- <mapping resource="com/future/test/User.hbm.xml" /> -->
  17. <mapping resource="com/future/domain/User.hbm.xml" />
  18. </session-factory>
  19. </hibernate-configuration>
  1. 只是一个例子,具体内容以后修改。
  2. <?xml version="1.0"?>
  3. <!DOCTYPE hibernate-mapping PUBLIC
  4. "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  5. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
  6. <hibernate-mapping package="com.future.domain">
  7. <class name="User" table="t_user">
  8. <id name="id" type="int">
  9. <column name="I_ID" />
  10. <generator class="native" />
  11. </id>
  12. <property name="name" type="java.lang.String" unique="false">
  13. <column name="S_NAME" />
  14. </property>
  15. <property name="loginName" type="java.lang.String">
  16. <column name="S_LOGINNAME" />
  17. </property>
  18. <property name="password" type="java.lang.String">
  19. <column name="S_PASSWORD" />
  20. </property>
  21. <property name="phoneNum" type="java.lang.String">
  22. <column name="S_PHONENUM" />
  23. </property>
  24. <!--
  25. repairHistorys:本类和repairHistory一对多
  26. -->
  27. <set name="repairHistorys">
  28. <key column="repairManId"></key>
  29. <one-to-many class="RepairHistory" />
  30. </set>
  31. </class>
  32. </hibernate-mapping>
4、添加spring环境 5个
核心包
依赖AOP
 子类代理
日志
之后考入配置文件:(注:这个配置文件必须自己手动创建,然后复制别人的内容)
 
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
  4. xmlns:tx="http://www.springframework.org/schema/tx"
  5. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  6. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
  7. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
  8. <!--自动扫描与装配bean 包含子包 -->
  9. <context:component-scan base-package="com.future"></context:component-scan>
  10. <!-- 导入外部得properties -->
  11. <context:property-placeholder location="classpath:jdbc.properties"/>
  12. </beans>
至此,jar包添加完毕
5、struts2与spring整合
写测试类
  1. package cn.itcast.test;
  2. import com.opensymphony.xwork2.ActionSupport;
  3. public class TestAction extends ActionSupport{
  4. public String execute() throws Exception{
  5. System.out.println("==>>testAction execute!!");
  6. return "success";
  7. }
  8. }
5.1之后配置测试页
 
  1. <%@ page language="java" contentType="text/html; charset=UTF-8"
  2. pageEncoding="UTF-8"%>
  3. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
  4. <html>
  5. <head>
  6. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  7. <title>Insert title here</title>
  8. </head>
  9. <body>
  10. struts2 添加成功!
  11. </body>
  12. </html>
struts2配置文件:
  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE struts PUBLIC
  3. "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
  4. "http://struts.apache.org/dtds/struts-2.3.dtd">
  5. <struts>
  6. <!-- 更改struts默认的主题 -->
  7. <constant name="struts.ui.theme" value="simple"/>
  8. <!-- 配置为开发模式 ,好处是修改过之后立即生效-->
  9. <constant name="struts.devMode" value="true"></constant>
  10. <!--声明包 -->
  11. <package name="defult" extends="struts-default">
  12. <!-- 配置测试用Action,为与spring整合,所以写全类名 -->
  13. <action name="test" class="cn.itcast.test.TestAction">
  14. <result name="success">Test.jsp</result>
  15. </action>
  16. <!-- <action name="product_*" class="com.atfuture.PM.action.ProductAction" method="{1}">
  17. <result name="list">/WEB-INF/jsp/product/product_list.jsp</result>
  18. <result name="success" type="redirect">/product_list</result>
  19. <result name="input">/WEB-INF/jsp/product/product_input.jsp</result>
  20. <result name="productStockAll">/WEB-INF/jsp/product/product_stock.jsp</result>
  21. <result name="cg_input">/WEB-INF/jsp/product/product_input.jsp</result>
  22. <result name="fintByCategory">/WEB-INF/jsp/product/product_cg_list.jsp</result>
  23. <result name="addinput">/WEB-INF/jsp/product/product_addinput.jsp</result>
  24. <result name="stockQuerySomeSuccess">/WEB-INF/jsp/product/someProduct.jsp</result>
  25. </action> -->
  26. </package>
  27. </struts>
 
如果报错:在web.xml中添加
  1. <!-- spring用于初始化容器对象得监听器配置监听器 -->
  2. <context-param>
  3. <param-name>contextConfigLocation</param-name>
  4. <param-value>classpath:applicationContext.xml</param-value>
  5. </context-param>
  6. <listener>
  7. <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  8. </listener>
 连个JSP页面放在WebContext下。
如果页面出现:
 并且访问test,出现
 代表struts2配置成功,
(整合与为整合主要看struts配置文件)
 
接下来测试spring
 
  1. package cn.itcast.test;
  2. import org.junit.Test;
  3. import org.springframework.context.ApplicationContext;
  4. import org.springframework.context.support.ClassPathXmlApplicationContext;
  5. public class SpringTest {
  6. private ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
  7. @Test
  8. public void TestSpring(){
  9. TestAction testAction = (TestAction) ctx.getBean("testAction");
  10. System.out.println(testAction);
  11. }
  12. }
不成功,因为还没有配置;
在这出现注解
 现在TestAction中添加注解
 spring扫描到这个Bean,
在applicationContext中添加自动扫描
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
  4. xmlns:tx="http://www.springframework.org/schema/tx"
  5. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  6. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
  7. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
  8. <!--自动扫描与装配bean 包含子包 -->
  9. <context:component-scan base-package="cn.itcast.test"></context:component-scan>
  10. <!-- 导入外部得properties -->
  11. <!-- <context:property-placeholder location="classpath:jdbc.properties"/> -->
  12. </beans>
输入
spring独立运行~~~
5.2接下来整合spring
5.2.1 添加spring监听(因为上面解决错误添加,现在就不用添加了)
 5.2.2添加整合jar包
 
5.2.3测试
 在测试页中添加一句话
 显示
 整合成功、
 
6、Hibernate与spring整合
6.1首先
在spring配置文件中 配置sessionFactory,
applicationContext文件,配置之前写属性文件
 
  1. jdbcUrl=jdbc:mysql:///carmanage?useUnicode=true&characterEncoding=utf8
  2. driverClass=com.mysql.jdbc.Driver
  3. user=root
  4. password=root
 
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
  4. xmlns:tx="http://www.springframework.org/schema/tx"
  5. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  6. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
  7. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
  8. <!--自动扫描与装配bean 包含子包 -->
  9. <context:component-scan base-package="cn.itcast.test"></context:component-scan>
  10. <!-- 导入外部得properties -->
  11. <context:property-placeholder location="classpath:jdbc.properties"/>
  12. <!--配置sessionFactory -->
  13. <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
  14. <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
  15. <property name="dataSource">
  16. <bean class="com.mchange.v2.c3p0.ComboPooledDataSource">
  17. <!-- 数据连接信息 -->
  18. <property name="jdbcUrl" value="${jdbcUrl}"></property>
  19. <property name="driverClass" value="${driverClass}"></property>
  20. <property name="user" value="${user}"></property>
  21. <property name="password" value="${password}"></property>
  22. <!-- 其他配置 -->
  23. <!--初始化时获取三个连接,取值应在minPoolSizemaxPoolSize之间。Default: 3 -->
  24. <property name="initialPoolSize" value="3"></property>
  25. <!--连接池中保留的最小连接数。Default: 3 -->
  26. <property name="minPoolSize" value="3"></property>
  27. <!--连接池中保留的最大连接数。Default: 15 -->
  28. <property name="maxPoolSize" value="5"></property>
  29. <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->
  30. <property name="acquireIncrement" value="3"></property>
  31. <!-- 控制数据源内加载的PreparedStatements数量。如果maxStatementsmaxStatementsPerConnection均为0,则缓存被关闭。Default: 0 -->
  32. <property name="maxStatements" value="8"></property>
  33. <!--maxStatementsPerConnection定义了连接池内单个连接所拥有的最大缓存statements数。Default: 0 -->
  34. <property name="maxStatementsPerConnection" value="5"></property>
  35. <!--最大空闲时间,1800秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
  36. <property name="maxIdleTime" value="1800"></property>
  37. </bean>
  38. </property>
  39. </bean>
  40. </beans>
在springTest测试文件中测试sessionFactory
 
  1. package cn.itcast.test;
  2. import org.hibernate.SessionFactory;
  3. import org.junit.Test;
  4. import org.springframework.context.ApplicationContext;
  5. import org.springframework.context.support.ClassPathXmlApplicationContext;
  6. public class SpringTest {
  7. private ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
  8. @Test
  9. public void TestSpring(){
  10. TestAction testAction = (TestAction) ctx.getBean("testAction");
  11. System.out.println(testAction);
  12. }
  13. @Test
  14. public void TestSessionFactory(){
  15. SessionFactory sessionFactory = (SessionFactory) ctx.getBean("sessionFactory");
  16. System.out.println(sessionFactory);
  17. }
  18. }
在这会出现一个错误,因为找不到hibernate得映射文件,在是之前复制得时候多复制了,现在把它注释掉
 在运行,成功~~
 6.2配置事务管理,在spring得配置文件applicationContext中配置。
  1. <!-- 配置声明式事物 -->
  2. <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
  3. <property name="sessionFactory" ref="sessionFactory"></property>
  4. </bean>
  5. <!-- 配置处理事务的注释 -->
  6. <tx:annotation-driven transaction-manager="transactionManager"/>
6.3配置测试用的javaBean
 
  1. package cn.itcast.domain;
  2. public class User {
  3. private Long id;
  4. private String name;
  5. public Long getId() {
  6. return id;
  7. }
  8. public void setId(Long id) {
  9. this.id = id;
  10. }
  11. public String getName() {
  12. return name;
  13. }
  14. public void setName(String name) {
  15. this.name = name;
  16. }
  17. }
6.4配置映射文件
 
  1. <?xml version="1.0"?>
  2. <!DOCTYPE hibernate-mapping PUBLIC
  3. "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  4. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
  5. <hibernate-mapping package="cn.itcast.domain">
  6. <class name="User" table="test_user">
  7. <id name="id" type="int">
  8. <column name="I_ID" />
  9. <generator class="native" />
  10. </id>
  11. <property name="name" type="java.lang.String" >
  12. <column name="S_NAME" />
  13. </property>
  14. </class>
  15. </hibernate-mapping>
在hibernate得配置文件中增加mapping
 6.5准备测试。
6.5.1首先建立server层
 
  1. package cn.itcast.test;
  2. import javax.annotation.Resource;
  3. import org.hibernate.Session;
  4. import org.hibernate.SessionFactory;
  5. import org.springframework.stereotype.Service;
  6. import org.springframework.transaction.annotation.Transactional;
  7. import cn.itcast.domain.User;
  8. @Service("testService")
  9. public class TestService {
  10. @Resource
  11. private SessionFactory sessionFactory;
  12. @Transactional
  13. public void saveTwoUse(){
  14. Session session = sessionFactory.getCurrentSession();
  15. session.save(new User());
  16. int a=1/0;
  17. session.save(new User());
  18. }
  19. }
 接下来测试事务,在springTest中添加
  1. @Test
  2. public void TestTransaction(){
  3. TestService testService = (TestService) ctx.getBean("testService");
  4. testService.saveTwoUse();
  5. }
提示,
 代表事务成功。
注释掉:
 
提示:
最后:完整测试
修改TestAction文件
 修改Test.jsp
 ,运行访问
提示
 
 
完全整合完成~
7、资源分类
7.1测试和主要内容分开,并且把配置文件放到一起
 7.2关于建包
 7.3关于资源
8、配置日志
 日志jar包
 最后,关于日志在视频中找~~~。
