SSM 整合系列之 SSM 项目整合
Spring、SpringMVC 和 MyBatis 已经是非常成熟的框架了,使用该框架开发已有些时日了,从今天开始呢就对用此框架开发的过程进行一系列的总结,旨在个人总结中提升自己,同时能帮到需要的人就更好了(大牛可忽略此文)。本文将着重介绍项目的搭建整合。 1 Maven Web 项目创建 2 SSM 整合 项目结构如下图: 2.1 web.xml 配置 webapp 下创建 WEB-INF 然后创建 web.xml 文件,文件内容如下:
```
<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring MVC servlet -->
<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*:servlet/*.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>
<session-config>
<session-timeout>30</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
```

2.3、数据库连接和 Log4j 配置 src-main-resource 下创建 config 文件夹,然后创建 jdbc.properties 文件,文件内容如下:
```
连接驱动
jdbc.driverClassName=com.mysql.jdbc.Driver
主库
jdbc.url = jdbc\:mysql\://localhost\:3306/db_ssmdemo?useUnicode\=true&characterEncoding\=UTF-8&allowMultiQueries\=true jdbc.username = root jdbc.password = 123456
jdbc.initialSize=2 jdbc.maxActive=5 jdbc.maxIdle=5 jdbc.minIdle=1 jdbc.validationQuery=select 1 ```
src-main-resource 创建文件 log4j.properties,文件内容如下:
``` log4j.rootLogger = DEBUG,stdout,A1,A2
STDOUT
log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
INFO
log4j.appender.A1 = org.apache.log4j.DailyRollingFileAppender log4j.appender.A1.File =../logs/info.log log4j.appender.A1.Append = true log4j.appender.A1.Threshold =INFO log4j.appender.A1.layout = org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
ERROR
log4j.appender.A2 = org.apache.log4j.DailyRollingFileAppender log4j.appender.A2.File =../logs/error.log log4j.appender.A2.Append = true log4j.appender.A2.Threshold =ERROR log4j.appender.A2.layout = org.apache.log4j.PatternLayout log4j.appender.A2.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
log4j.logger.com.ibatis=DEBUG log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG log4j.logger.org.mybatis=DEBUG log4j.logger.java.sql.Connection=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG log4j.logger.java.sql.ResultSet=DEBUG ```
2.4Spring 配置 src-main-resource 下创建 Spring 文件夹,然后创建 applicationContext.xml 文件
```
<?xml version="1.0" encoding="UTF-8"?>
<!--引入配置属性文件 -->
<context:property-placeholder location="classpath*:config/*.properties" />
<!-- 线程池配置 -->
<bean id="taskExecutor" class="uc6_0270_70fec12 org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<!-- 核心线程数 -->
<property name="corePoolSize" value="5"/>
<!-- 最大线程数 -->
<property name="maxPoolSize" value="50"/>
<!-- 队列最大长度 -->
<property name="queueCapacity" value="1000"/>
<!-- 线程池维护线程所允许的空闲时间,默认为60s -->
<property name="keepAliveSeconds" value="6"/>
</bean>
```
2.5 数据源配置 Spring 文件加下创建 dataAccessContext.xml 文件
```
<!-- 数据源-->
<bean id="dataSource" class="v0a_d4c7_c7edaaf com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialSize" value="${jdbc.initialSize}" />
<property name="maxActive" value="${jdbc.maxActive}" />
<property name="maxIdle" value="${jdbc.maxIdle}" />
<property name="minIdle" value="${jdbc.minIdle}" />
<property name="validationQuery" value="${jdbc.validationQuery}" />
<!-- 监控数据库 -->
<!--<property name="filters" value="mergeStat" />-->
<property name="filters" value="stat" />
<property name="connectionProperties" value="druid.stat.mergeSql=true" />
</bean>
```
2.6 MyBatis 配置 Spring 文件加下创建 mybatis.xml 文件,该文件为 Spring 和 MyBatis 整合内容
```
<bean id="sqlSessionFactory" > <property name="dataSource" ref="dataSource" /> <property name="mapperLocations"> <list> <value>classpath:sql/*.xml</value> </list> </property> </bean> <bean > <property name="basePackage" value="com.ssm.mapper" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <bean id="sqlSession" scope="prototype"> <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> <!-- 使用annotation定义事务,使用cglib代理,解决同一service中事务方法相互调用的 嵌套事务失效问题 --> <tx:annotation-driven transaction-manager="transactionManager" proxy-target-/> <!--事务配置 --> <bean id="transactionManager" > <property name="dataSource" ref="dataSource" /> </bean>
```
2.7 整合 SpringMVC src-main-resource 下创建 servlet 文件夹,然后创建 spring-mvc.xml 文件
```
<!-- 自动扫描,只扫描Controller --> <context:component-scan base-package="com.ssm"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /> </context:component-scan> <!-- 启用spring mvc 注解 --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- 将StringHttpMessageConverter的默认编码设为UTF-8 --> <bean > <constructor-arg value="UTF-8" /> </bean> <bean /> <!-- 将Jackson2HttpMessageConverter的默认格式化输出设为true --> <bean > <property name="prettyPrint" value="true"/> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 静态资源 --> <!-- <mvc:resources mapping="/static/**" location="/static/" /> --> <!-- 试图解析后台 --> <bean > <property name="prefix" value="/WEB-INF/views" /> <property name="suffix" value=".jsp" /> <property name="order" value="1" /> </bean> <!-- 配置多文件上传 --> <bean id="multipartResolver" > <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <!-- 上传文件大小限制为100M,100*1024*1024 --> <value>104857600</value> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean>
```
2.8 创建 index.jsp 页面 在 webapp 创建 index.jsp 页面
``` <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
index.jsp
```
2.9 创建一个测试 Controller,类为 HelloController
``` package com.ssm.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping("test") public class HelloController {
@RequestMapping("hello")
@ResponseBody
public String hello() {
return "hello";
}
} ```
访问 http://IP 地址:端口号/SSM_DEMO/test/hello,即可查看返回值,正常返回,说明项目搭建成功
