SSM 框架-05-詳細整合教程(Eclipse版)(Spring+SpringMVC+MyBatis)
如果你使用的是 Intellij IDEA，請查看：
SSM的配置流程詳細的寫了出來，方便很少接觸這個框架的朋友使用，文中各個資源均免費提供！
一.創建web項目（eclipse）
File-->new-->Dynamic Web Project (這里我們創建的項目名為SSM)
下面是大致目錄結構
二. SSM所需jar包。
jar包鏈接：https://pan.baidu.com/s/1dTClhO 密碼：n4mm
三.整合開始
1.mybatis配置文件（resource/mybatis/SqlMapConfig.xml）
-
<?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>
-
-
</configuration>
2.Dao，mybatis整合spring，通過spring管理
SqlSessionFactory、mapper代理對象
（resource/spring/applicationContext-dao.xml）
-
<?xml version="1.0" encoding="UTF-8"?>
-
<beans xmlns="http://www.springframework.org/schema/beans"
-
xmlns:context=
"http://www.springframework.org/schema/context"
xmlns:p=
"http://www.springframework.org/schema/p"
-
xmlns:aop=
"http://www.springframework.org/schema/aop"
xmlns:tx=
"http://www.springframework.org/schema/tx"
-
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
-
xsi:schemaLocation=

-
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
-

-
<!-- 數據庫連接池 -->
-
<!-- 加載配置文件 -->
-
<context:property-placeholder location="classpath:*.properties" />
-
<!-- 數據庫連接池 -->
-
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
-
destroy-method=
"close">
-
<property name="url" value="${jdbc.url}" />
-
<property name="username" value="${jdbc.username}" />
-
<property name="password" value="${jdbc.password}" />
-
<property name="driverClassName" value="${jdbc.driver}" />
-
<property name="maxActive" value="10" />
-
<property name="minIdle" value="5" />
-
</bean>
-
<!-- 讓spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
-
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
-
<!-- 數據庫連接池 -->
-
<property name="dataSource" ref="dataSource" />
-
<!-- 加載mybatis的全局配置文件 -->
-
<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
-
</bean>
-
<!-- 自動掃描 將Mapper接口生成代理注入到Spring -->
-
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
-
<property name="basePackage" value="com.mapper" />
-
</bean>
-
</beans>
這里用的是阿里的連接池，當然也可以用c3p0，個人建議用阿里
3. 所有的實現類都放到spring容器中管理。由spring創建數據庫連接池，並有spring管理實務。
（resource/spring/applicationContext-service.xml）
-
<?xml version="1.0" encoding="UTF-8"?>
-
<beans xmlns="http://www.springframework.org/schema/beans"

-
-
<!-- spring自動去掃描base-pack下面或者子包下面的java文件-->
-
<!--管理Service實現類-->
-
<context:component-scan base-package="com.service"/>

配置spring管理實務
（resource/spring/applicationContext-trans.xml）
-
<?xml version="1.0" encoding="UTF-8"?>
-
<beans xmlns="http://www.springframework.org/schema/beans"
-
xmlns:context=

<aop:config>
-
<aop:advisor advice-ref="txAdvice"
-
pointcut=
"execution(* com.service.*.*(..))" />
-
</aop:config>
-
</beans>
4. Springmvc整合spring框架，由springmvc管理controller
（resource/spring/springmvc.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:p=
"http://www.springframework.org/schema/p"
-
xmlns:context=
"http://www.springframework.org/schema/context"
-
xmlns:mvc=
"http://www.springframework.org/schema/mvc"
-
xsi:schemaLocation=
"http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
-
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
-
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
-
-
<!-- 掃描controller -->
-
<context:component-scan base-package="com.controller" />
-
-
<!-- Spring 來掃描指定包下的類，並注冊被@Component，@Controller，@Service，@Repository等注解標記的組件 -->
-
<mvc:annotation-driven />
-
-
<!-- 配置SpringMVC的視圖解析器-->
-
<bean
-
class=
"org.springframework.web.servlet.view.InternalResourceViewResolver">
-
<property name="prefix" value="/WEB-INF/jsp/" />
-
<property name="suffix" value=".jsp" />
-
</bean>
-
</beans>
5. 2中加載的屬性配置文件（dbconfig.properties）
根據自己的數據庫更改用戶名密碼以及庫
-
jdbc.driver=com.mysql.jdbc.Driver
-
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
-
jdbc.username=root
-
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>
-
</appender>
-
-
<!-- Application Loggers -->
-
<logger name="com">
-
<level value="error" />
-
</logger>
-
-
<!-- 3rdparty Loggers -->
-
<logger name="org.springframework.core">
-
<level value="error" />
-
</logger>
-
-
<logger name="org.springframework.beans">
-
<level value="error" />
-
</logger>
-
-
<logger name="org.springframework.context">
-

-
</logger>
-
-
<logger name="org.springframework.web">
-
<level value="error" />
-
</logger>
-
-
<logger name="org.springframework.jdbc">

-
</logger>
-
-
<logger name="org.mybatis.spring">

-
</logger>
-
<!-- Root Logger -->
-
<root>
-
<priority value="error" />
-
<appender-ref ref="console" />
-
</root>
-
-
</log4j:configuration>
SSM框架整合完成，至於mybatis逆向工程生成的mapper.xml和pojo請放到第一張圖的目錄下
注：逆向工程是根據數據庫表反向生成pojo以及mapper.xml，所以，請先自動在數據庫配置好user表。逆向工程得配置在下面得鏈接里面有詳細注釋。
測試數據庫表（User）
private String id;
private String username;
private String password;
private String company;
private Integer age;
private Integer sex;
根據類型創建表即可
逆向工程項目我會貼出鏈接，解壓導入改路徑運行main方法就會自動生成了，注意配置生成的路徑

到這里項目整合完成，接下來是測試！
UserController.java
-
package com.controller;
-
-
import javax.annotation.Resource;
-
import javax.servlet.http.HttpServletRequest;
-
import org.springframework.stereotype.Controller;
-
import org.springframework.web.bind.annotation.RequestMapping;
-
import org.springframework.web.servlet.ModelAndView;
-
import com.pojo.User;
-
import com.service.UserService;
-
-
@Controller
-
@RequestMapping(
"/user")
-
public
class UserController {
-
-
@Resource(name=
"userService")
-
private UserService userService;
-
/**
-
* 根據id查詢
-
*/
-
@RequestMapping(value=
"/queryById")
-
public ModelAndView queryById(HttpServletRequest request){
-
ModelAndView mv =
new ModelAndView();
-
String id = request.getParameter(
"id");
-
try{
-
User var = userService.findById(id);
-
mv.setViewName(
"index");
-
mv.addObject(
"var", var);
-
}
catch(Exception e){
-
e.printStackTrace();
-
}
-
return mv;
-
}
-
}
UserService.java
-
package com.service;
-
-
import javax.annotation.Resource;
-
-
import org.springframework.stereotype.Service;
-
-
import com.mapper.UserMapper;
-
import com.pojo.User;
-
-
@Service(
"userService")
-
public
class UserService {
-
@Resource
-
private UserMapper dao;
-
/*
-
* 通過id獲取數據
-
*/
-
public User findById(String id)throws Exception{
-
return (User)dao.selectByPrimaryKey(id);
-
}
-
}
補上之前漏掉得web.xml配置
-
<?xml version="1.0" encoding="UTF-8"?>
-
