SSM框架搭建2(spring+springmvc+mybatis)

SSM框架搭建(spring+springmvc+mybatis)

 自己配置了一个SSM框架,打算做个小网站,这里把SSM的配置流程详细的写了出来,方便很少接触这个框架的朋友使用,文中各个资源均免费提供!(后续读写分离:https://blog.csdn.net/dwhdome/article/details/83380149

一.创建web项目(eclipse)

 File-->new-->Dynamic Web Project (这里我们创建的项目名为SSM)

下面是大致目录结构

 

 

 

二. SSM所需jar包。

 

 jar包链接:https://pan.baidu.com/s/1dTClhO 密码:n4mm

 

三.整合开始

 

1.mybatis配置文件(resource/mybatis/SqlMapConfig.xml)

  1.  
    <?xml version="1.0" encoding="UTF-8" ?>
  2.  
    <!DOCTYPE configuration
  3.  
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4.  
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
  5.  
    <configuration>
  6.  
     
  7.  
    </configuration>

2.Dao,mybatis整合spring,通过spring管理

SqlSessionFactory、mapper代理对象

(resource/spring/applicationContext-dao.xml)

 

  1.  
    <?xml version="1.0" encoding="UTF-8"?>
  2.  
    <beans xmlns="http://www.springframework.org/schema/beans"
  3.  
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  4.  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
  5.  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  6.  
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
  7.

  8.  
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
  9.  
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
  10.  
     
  11.  
    <!-- 数据库连接池 -->
  12.  
    <!-- 加载配置文件 -->
  13.  
    <context:property-placeholder location="classpath:*.properties" />
  14.  
    <!-- 数据库连接池 -->
  15.  
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
  16.  
    destroy-method="close">
  17.  
    <property name="url" value="${jdbc.url}" />
  18.  
    <property name="username" value="${jdbc.username}" />
  19.  
    <property name="password" value="${jdbc.password}" />
  20.  
    <property name="driverClassName" value="${jdbc.driver}" />
  21.  
    <property name="maxActive" value="10" />
  22.  
    <property name="minIdle" value="5" />
  23.  
    </bean>
  24.  
    <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
  25.  
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  26.  
    <!-- 数据库连接池 -->
  27.  
    <property name="dataSource" ref="dataSource" />
  28.  
    <!-- 加载mybatis的全局配置文件 -->
  29.  
    <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
  30.  
    </bean>
  31.  
    <!-- 自动扫描 将Mapper接口生成代理注入到Spring -->
  32.  
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  33.  
    <property name="basePackage" value="com.mapper" />
  34.  
    </bean>
  35.  
    </beans>

 

这里用的是阿里的连接池,当然也可以用c3p0,个人建议用阿里

 

3. 所有的实现类都放到spring容器中管理。由spring创建数据库连接池,并有spring管理实务。

(resource/spring/applicationContext-service.xml)

  1.  
    <?xml version="1.0" encoding="UTF-8"?>
  2.  
    <beans xmlns="http://www.springframework.org/schema/beans"
  3.  
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  4.  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
  5.  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  6.  
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

  9.  
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
  10.  
     
  11.  
    <!-- spring自动去扫描base-pack下面或者子包下面的java文件-->
  12.  
    <!--管理Service实现类-->
  13.  
    <context:component-scan base-package="com.service"/>
  14.  
    </beans>

配置spring管理实务

 (resource/spring/applicationContext-trans.xml)

  1.  
    <?xml version="1.0" encoding="UTF-8"?>
  2.  
    <beans xmlns="http://www.springframework.org/schema/beans"
  3.  
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  4.  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
  5.  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  6.  
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

  9.  
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
  10.  
    <!-- 事务管理器 -->
  11.  
    <bean id="transactionManager"
  12.  
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  13.  
    <!-- 数据源 -->
  14.  
    <property name="dataSource" ref="dataSource" />
  15.  
    </bean>
  16.  
    <!-- 通知 -->
  17.  
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
  18.  
    <tx:attributes>
  19.  
    <!-- 传播行为 -->
  20.  
    <tx:method name="save*" propagation="REQUIRED" />
  21.  
    <tx:method name="insert*" propagation="REQUIRED" />
  22.  
    <tx:method name="add*" propagation="REQUIRED" />
  23.  
    <tx:method name="create*" propagation="REQUIRED" />
  24.

  28.  
    <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
  29.  
    </tx:attributes>
  30.  
    </tx:advice>
  31.  
    <!-- 切面 -->
  32.  
    <aop:config>
  33.  
    <aop:advisor advice-ref="txAdvice"
  34.  
    pointcut="execution(* com.service.*.*(..))" />
  35.  
    </aop:config>
  36.  
    </beans>

4. Springmvc整合spring框架,由springmvc管理controller

(resource/spring/springmvc.xml)

  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:p="http://www.springframework.org/schema/p"
  4.  
    xmlns:context="http://www.springframework.org/schema/context"
  5.  
    xmlns:mvc="http://www.springframework.org/schema/mvc"
  6.  
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
  7.  
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
  8.  
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
  9.  
     
  10.  
    <!-- 扫描controller -->
  11.  
    <context:component-scan base-package="com.controller" />
  12.  
     
  13.  
    <!-- Spring 来扫描指定包下的类,并注册被@Component,@Controller,@Service,@Repository等注解标记的组件 -->
  14.  
    <mvc:annotation-driven />
  15.  
     
  16.  
    <!-- 配置SpringMVC的视图解析器-->
  17.  
    <bean
  18.  
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  19.  
    <property name="prefix" value="/WEB-INF/jsp/" />
  20.  
    <property name="suffix" value=".jsp" />
  21.  
    </bean>
  22.  
    </beans>

5. 2中加载的属性配置文件(dbconfig.properties)

根据自己的数据库更改用户名密码以及库

  1.  
    jdbc.driver=com.mysql.jdbc.Driver
  2.  
    jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
  3.  
    jdbc.username=root
  4.  
    jdbc.password=123456

 

6. 配置log4j

(log4j.properties)

log4j.rootLogger=error,CONSOLE,A
log4j.addivity.org.apache=false

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=error
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} -%-4r [%t] %-5p  %x - %m%n
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=gbk
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout


log4j.appender.A=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.A.File=${catalina.home}/logs/FH_log/PurePro_
log4j.appender.A.DatePattern=yyyy-MM-dd'.log'
log4j.appender.A.layout=org.apache.log4j.PatternLayout  
log4j.appender.A.layout.ConversionPattern=[FH_sys]  %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}\:%L \: %m%n


 (log4j.xml)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

	<!-- Appenders -->
	<appender name="console" class="org.apache.log4j.ConsoleAppender">

		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{yyyy HH:mm:ss} %-5p %c - %m%n" />
		</layout>
	</appender>
	
	<!-- Application Loggers -->
	<logger name="com">
		<level value="error" />
	</logger>
	
	<!-- 3rdparty Loggers -->
	<logger name="org.springframework.core">

	</logger>	
	
	<logger name="org.springframework.beans">
		<level value="error" />
	</logger>
	
	<logger name="org.springframework.context">

	</logger>

	<logger name="org.springframework.web">

	</logger>
	<!-- Root Logger -->
	<root>
		<priority value="error" />
		<appender-ref ref="console" />
	</root>
	
</log4j:configuration>

 SSM框架整合完成,至于mybatis逆向工程生成的mapper.xml和pojo请放到第一张图的目录下

注:逆向工程是根据数据库表反向生成pojo以及mapper.xml,所以,请先自动在数据库配置好user表。逆向工程得配置在下面得链接里面有详细注释。

测试数据库表(User)

    private String id;

    private String username;

    private String password;

    private String company;

    private Integer age;

    private Integer sex;

根据类型创建表即可

 

逆向工程项目我会贴出链接,解压导入改路径运行main方法就会自动生成了,注意配置生成的路径

到这里项目整合完成,接下来是测试!
 UserController.java

  1.  
    package com.controller;
  2.  
     
  3.  
    import javax.annotation.Resource;
  4.  
    import javax.servlet.http.HttpServletRequest;
  5.  
    import org.springframework.stereotype.Controller;
  6.  
    import org.springframework.web.bind.annotation.RequestMapping;
  7.  
    import org.springframework.web.servlet.ModelAndView;
  8.  
    import com.pojo.User;
  9.  
    import com.service.UserService;
  10.  
     
  11.  
    @Controller
  12.  
    @RequestMapping("/user")
  13.  
    public class UserController {
  14.  
     
  15.  
    @Resource(name="userService")
  16.  
    private UserService userService;
  17.  
    /**
  18.  
    * 根据id查询
  19.  
    */
  20.  
    @RequestMapping(value="/queryById")
  21.  
    public ModelAndView queryById(HttpServletRequest request){
  22.  
    ModelAndView mv = new ModelAndView();
  23.  
    String id = request.getParameter("id");
  24.  
    try{
  25.  
    User var = userService.findById(id);
  26.  
    mv.setViewName("index");
  27.  
    mv.addObject("var", var);
  28.  
    } catch(Exception e){
  29.  
    e.printStackTrace();
  30.  
    }
  31.  
    return mv;
  32.  
    }
  33.  
    }

UserService.java

  1.  
    package com.service;
  2.  
     
  3.  
    import javax.annotation.Resource;
  4.  
     
  5.  
    import org.springframework.stereotype.Service;
  6.  
     
  7.  
    import com.mapper.UserMapper;
  8.  
    import com.pojo.User;
  9.  
     
  10.  
    @Service("userService")
  11.  
    public class UserService {
  12.  
    @Resource
  13.  
    private UserMapper dao;
  14.  
    /*
  15.  
    * 通过id获取数据
  16.  
    */
  17.  
    public User findById(String id)throws Exception{
  18.  
    return (User)dao.selectByPrimaryKey(id);
  19.  
    }
  20.  
    }

 

补上之前漏掉得web.xml配置
