SSM框架搭建2(spring+springmvc+mybatis)
SSM框架搭建(spring+springmvc+mybatis)
置頂2018年01月23日 16:10:38丁文浩閱讀數:55506自己配置了一個SSM框架,打算做個小網站,這裡把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!(後續讀寫分離:https://blog.csdn.net/dwhdome/article/details/83380149)
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)
- <configuration>
- </configuration>
2.Dao,mybatis整合spring,通過spring管理
SqlSessionFactory、mapper代理物件
(resource/spring/applicationContext-dao.xml)
- <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)
- <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/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)
- <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">
- <!-- 事務管理器 -->
- <bean id="transactionManager"
- class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
- <!-- 資料來源 -->
- <property name="dataSource" ref="dataSource" />
- </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)
- <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"> <level value="error" /> </logger> <logger name="org.springframework.web"> <level value="error" /> </logger> <logger name="org.springframework.jdbc"> <level value="error" /> </logger> <logger name="org.mybatis.spring"> <level value="error" /> </logger> <logger name="java.sql"> <level value="error" /> </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;
- public class UserController {
- private UserService userService;
- /**
- * 根據id查詢
- */
- 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;
- public class UserService {
- 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
- <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>
