SSM整合记录
就想自己折腾，把框架聚合起来，然后发现公司的框架配置，其实官网基本都写详细了。
结合官网文档，很快可以搭出来的。不懂再看下公司项目配置，美滋滋....
参考文档：

1.先来全家福：
以及数据库：
2. pom.xml配置：

3. web.xml配置：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:spring-application.xml, classpath*:spring-mybatis.xml </param-value> </context-param> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:spring-mvc.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 注意 /XX/* /* *.XX 的区别（* 和/*.do 报错了，为什么呢）--> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/hehe/*</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 编码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
4. spring-application.xml 这里只用来了扫描service和dao 注解：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- Bean 扫描，过滤Controller(这个在spring-mvc.xml里扫描) --> <context:component-scan base-package="com.renzku"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> </beans>
5. spring-mvc.xml:

6. jdbc.properties:
db.driver=com.mysql.jdbc.Driver db.host=localhost db.databaseName=myssm db.url=jdbc:mysql://${db.host}:3306/${db.databaseName}?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull db.username=root db.password=123456 db.maximum.connection.count=100 db.minimum.connection.count=1 db.simultaneous.build.throttle=3
7.mybatis-config.xml,这些个属性含义，mybatis官网很详细:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="cacheEnabled" value="true"/> <setting name="lazyLoadingEnabled" value="true"/> <setting name="multipleResultSetsEnabled" value="true"/> <setting name="useColumnLabel" value="true"/> <setting name="useGeneratedKeys" value="true"/> <setting name="autoMappingBehavior" value="PARTIAL"/> <setting name="autoMappingUnknownColumnBehavior" value="WARNING"/> <setting name="defaultExecutorType" value="SIMPLE"/> <setting name="defaultStatementTimeout" value="2500"/> <setting name="defaultFetchSize" value="100"/> <setting name="safeRowBoundsEnabled" value="false"/> <setting name="mapUnderscoreToCamelCase" value="false"/> <setting name="localCacheScope" value="SESSION"/> <setting name="jdbcTypeForNull" value="NULL"/> <setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString"/> </settings> </configuration>
8.spring-mybatis.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 加载jdbc配置文件 --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations" value="classpath:jdbc.properties"/> </bean> <!-- 配置数据源 --> <bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource"> <property name="alias" value="proxoolDataSource"/> <property name="driver" value="${db.driver}"/> <property name="driverUrl" value="${db.url}"/> <property name="user" value="${db.username}"/> <property name="password" value="${db.password}"/> <property name="maximumConnectionCount" value="${db.maximum.connection.count}"/> <property name="minimumConnectionCount" value="${db.minimum.connection.count}"/> <property name="simultaneousBuildThrottle" value="${db.simultaneous.build.throttle}"/> </bean> <!-- SqlSessionFactory配置和加载mapper映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:mybatis-config.xml"/> <property name="mapperLocations" value="classpath*:config/mapper/**/*.xml"/> </bean> <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory" /> <constructor-arg index="1" value="BATCH" /> </bean> <!-- 事务配置 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- the transactional advice (what 'happens'; see the <aop:advisor/> bean below) --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- the transactional semantics... --> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true"/> <tx:method name="find*" read-only="true"/> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*"/> </tx:attributes> </tx:advice> <!-- ensure that the above transactional advice runs for any execution of an operation defined by the FooService interface --> <aop:config> <aop:pointcut id="fooServiceOperation" expression="execution(* com.renzku.service..*.*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="fooServiceOperation"/> </aop:config> </beans>
9.实体类SysUser.java:
package com.renzku.POJO; /** * Created by renzku on 2017/9/9. */ public class SysUser { private Long userId; private String userName; private String userText; public SysUser() { } public SysUser(Long userId, String userName, String userText) { this.userId = userId; this.userName = userName; this.userText = userText; } public Long getUserId() { return userId; } public void setUserId(Long userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserText() { return userText; } public void setUserText(String userText) { this.userText = userText; } }
10.userMapper.xml映射文件：
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="renkzu.config.mapper.userMapper"> <resultMap id="commonResult" type="com.renzku.POJO.SysUser"> <result column="user_id" property="userId" jdbcType="BIGINT"/> <result column="user_name" property="userName" jdbcType="VARCHAR"/> <result column="user_text" property="userText" jdbcType="VARCHAR"/> </resultMap> <select id="findSysUserAllList" resultMap="commonResult"> SELECT * from myssm_user </select> </mapper>
11.SysUserDaoImpl.java：
这里说下，这里配置数据库访问用的SqlSessionDaoSupport。
所以在访问时（比如selectList(String namespace [,Object obj])）,至少需要传入mapper.xml的namespace；
所以这里的findSysUserAllList()中sqlName变量为 "renzku.config.mapper.userMapper.XX",与userMapper.xml中的namespace一致；
就是：
1.这个可以随便取名字，只要两处保持相同即可；
2.有另外一种配置方式：不用SqlSessionDaoSupport的，只写Dao的 interface，然后跟userMapper.xml关联，这个userMapper.xml就必须写Dao的包路径加文件名称。
package com.renzku.dao.impl; import com.renzku.POJO.SysUser; import com.renzku.dao.SysUserDao; import org.mybatis.spring.SqlSessionTemplate; import org.mybatis.spring.support.SqlSessionDaoSupport; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; import java.util.List; /** * Created by renzku on 2017/9/9. */ @Repository public class SysUserDaoImpl extends SqlSessionDaoSupport implements SysUserDao { @Autowired @Override public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) { super.setSqlSessionTemplate(sqlSessionTemplate); } public List<SysUser> findSysUserAllList() { String sqlName="renkzu.config.mapper.userMapper"+".findSysUserAllList"; return this.getSqlSession().selectList(sqlName); } }
12.HelloWorldController.java:
package com.renzku.controller; import com.renzku.POJO.SysUser; import com.renzku.service.SysUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import java.util.List; /** * Created by renzku on 2017/9/6. */ @Controller public class HelloWorldController { @Autowired private SysUserService sysUserService; @RequestMapping(value = "/helloWorld") public String helloWorld(Model model) { // 直接一直调用到SysUserDaoImpl.findSysUserAllList List<SysUser> userlist=this.sysUserService.findSysUserAllList(); model.addAttribute("ssm", userlist.get(0)); return "helloWorld"; } }
13.helloWorld.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <body> <h2>Hello World!</h2> <h3>yayaay:${ssm.userName}</h3> </body> </html>
14.效果：
访问 http://localhost:8081/myssm/hehe/helloWorld
显示 ：

20170909：
上面spring-mybatis.xml事务配置那里，没完成呢。
添加 rollback-for才行，添加后，service方法中抛出对应异常，则可以引起事务回滚。
另外IllegalArgumentException继承自Exception,抛出它也会引起rollback-for=“Exception”的回滚。
<tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- the transactional semantics... --> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true"/> <tx:method name="find*" read-only="true"/> <tx:method name="update*" rollback-for="Exception"/> <tx:method name="delete*" rollback-for="IllegalArgumentException"/> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*" propagation="REQUIRED" rollback-for="Exception"/> </tx:attributes> </tx:advice>
