SSM框架搭建(spring+springmvc+mybatis)
一.建立web專案(eclipse)
File-->new-->Dynamic Web Project (這裡我們建立的專案名為SSM)
下面是大致目錄結構
二. SSM所需jar包。
jar包連結:https://pan.baidu.com/s/1dTClhO 密碼:n4mm
三.整合開始
1.mybatis配置檔案(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代理物件
(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/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 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 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 資料庫連線池 --> <!-- 載入配置檔案 --> <context:property-placeholder location="classpath:*.properties" /> <!-- 資料庫連線池 --> <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"> <!-- 資料庫連線池 --> <property name="dataSource" ref="dataSource" /> <!-- 載入mybatis的全域性配置檔案 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> </bean> <!-- 自動掃描 將Mapper介面生成代理注入到Spring --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.mapper" /> </bean> </beans>
這裡用的是阿里的連線池,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建立資料庫連線池,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" 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/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 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 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- spring自動去掃描base-pack下面或者子包下面的java檔案--> <!--管理Service實現類--> <context:component-scan base-package="com.service"/> </beans>
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="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
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
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<!-- 事務管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 資料來源 -->

</bean>
<!-- 通知 -->

</tx:attributes>
</tx:advice>
<!-- 切面 -->
<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,並註冊被@Component,@Controller,@Service,@Repository等註解標記的元件 -->
<mvc:annotation-driven />
<!-- 配置SpringMVC的檢視解析器-->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
5. 2中載入的屬性配置檔案(dbconfig.properties)
根據自己的資料庫更改使用者名稱密碼以及庫
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">
<param name="Target" value="System.out" />
<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">
<level value="error" />
</logger>
<logger name="org.springframework.beans">
<level value="error" />
</logger>
<logger name="org.springframework.context">

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

</logger>
<logger name="org.springframework.jdbc">

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

</logger>
<logger name="java.sql">

</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:逆向工程是根據資料庫表反向生成pojo以及mapper.xml,所以,請先自動在資料庫配置好user表。逆向工程得配置在下面得連結裡面有詳細註釋。
測試資料庫表(User)
private String id;
private String username;
private String password;
private String company;
private Integer age;
private Integer sex;
根據型別建立表即可
逆向工程專案我會貼出連結,解壓匯入改路徑執行main方法就會自動生成了,注意配置生成的路徑
逆向工程連結: 連結:https://pan.baidu.com/s/1QvSskH2UEC6EQF7MgVDOAQ 密碼:t2pc
到這裡專案整合完成,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獲取資料
*/
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"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 載入spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 解決post亂碼 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>

<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>
<!-- springmvc的前端控制器 -->
<!-- <servlet>
<servlet-name>taotao-manager</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
contextConfigLocation不是必須的, 如果不配置contextConfigLocation, springmvc的配置檔案預設在:WEB-INF/servlet的name+"-servlet.xml"
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SSM</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> -->
<servlet>
<servlet-name>springMvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
為節省篇幅,更快的搭建成功,這裡只寫了一個方法,根據id查詢資料
