SSM(Spring+Spring MVC+Mybatis)环境框架搭建与配置详解

创建时间：2016-09-13 投稿人： 浏览次数：15483

使用SSM框架做了一些项目，一直都是使用别人已经搭建好的框架。于是自己尝试着搭建了一下框架，并研究了一下配置文件。


基本的组织结构和用法就不用多说了，各种官方文档上比较全面



开发环境MyEclipse+JDK1.7+Tomcat7

开发环境配置请查阅博客


本文按照开发环境搭建，完整的结构框架如下





1.web.xml

web.xml应该是整个项目中最重要的配置文件了，配置方式与普通的servlet基本相似

<span style="font-size:14px;">  <servlet>
    <servlet-name>mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:resources/spring-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping></span>

servlet 配置前端控制器，其中

ContextconfigLocation配置配置springmvc加载的配置文件适配器、处理映射等等

url-pattern中 .* ：访问以.*结尾 由DispatcherServlet进行解析

/  ：所有访问由DispatcherServlet进行解析


配置Spring容器：

<span style="font-size:14px;">  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:resources/spring-mvc.xml</param-value>
  </context-param></span>
配置日志文件： 

<span style="font-size:14px;">  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
  </context-param>
  <context-param>
    <param-name>log4jRefreshInterval</param-name>
    <param-value>60000</param-value>
  </context-param></span>

配置监听器： 

<span style="font-size:14px;">  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener></span>


配置容器编码为utf-8： 

<span style="font-size:14px;">  <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></span>

配置处理错误页面： 

<span style="font-size:14px;"><error-page>
<span style="white-space:pre">	</span><exception-type>java.lang.Throwable</exception-type>
<span style="white-space:pre">	</span><location>/error.jsp</location>
</error-page>
<error-page>
<span style="white-space:pre">	</span><error-code>404</error-code>
<span style="white-space:pre">	</span><location>/error.jsp</location>
</error-page>
<error-page>
<span style="white-space:pre">	</span><error-code>500</error-code>
<span style="white-space:pre">	</span><location>/error.jsp</location>
</error-page></span>

完整的web.xml文件如下： 

<span style="font-size:14px;"><?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" version="2.5" id="WebApp_1473651077644">
  <error-page>

4.jdbc.properties与log4j.properties

1.jdbc.properties

<span style="font-size:14px;">jdbc.driver =com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://yourUrl:3306/test?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=UTF-8
jdbc.user =yourName
jdbc.password = yourPwd
jdbc.maxActive=20</span>


2.log4j.properties


<span style="font-size:14px;">log4j.rootLogger=DEBUG,stdout,E
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p]%d{yyyy-MM-dd HH:mm:ss}[%c]:%m%n
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.com.mchange.v2.c3p0=OFF
log4j.logger.com.mchange.v2=OFF
log4j.logger.org.springframework=OFF
log4j.logger.org.mybatis=OFF
log4j.logger.org.apache.ibatis=OFF
log4j.logger.org.apache.http=OFF

# error
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = D:/logs/error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern =[%-5p]%d{yyyy-MM-dd HH:mm:ss}[%c]:%m%n</span>



base：定义基础操作和基础类，一般具体操作和几次实体都继承自此结构下的接口

controller：控制层

dao：数据库持久层

handler：定义具体逻辑与操作

schema：实体，一般与数据库中各表的具体字段对应

util：工具类

resource：配置工具，包含mybatis的mapper映射文件，对数据库具体操作在此文件中

数据库中保存如下数据



mapper映射文件如下：

<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.changhong.lyc.dao.TestDao">
	<resultMap id="BaseResultMap" type="com.changhong.lyc.schema.TestSchema">
		<id column="t_id" property="id" jdbcType="VARCHAR"/>
		<result column="t_name" property="name" jdbcType="VARCHAR"/>
		<result column="t_age" property="age" jdbcType="INTEGER"/>
		<result column="t_sex" property="sex" jdbcType="INTEGER"/>
		<result column="t_graduateYear" property="graduateYear" jdbcType="VARCHAR"/>
		<result column="t_collegeName" property="collegeName" jdbcType="VARCHAR"/>
	</resultMap>
  
 	<select id="selectOneByCondition" resultMap="BaseResultMap">
		select
				*
		from
			t_table
		where
			<if	test="name != null">
				t_name = #{name,jdbcType=VARCHAR}
			</if>
			<if	test="graduateYear != null">
				and t_graduateYear = #{graduateYear,jdbcType=VARCHAR}
			</if>
	</select>	
</mapper></span>


使用Postman测试


访问地址在controller视图控制类中定义


返回结果如下：

<span style="font-size:14px;">{
  "code": "1000",
  "data": {
    "age": 26,
    "collegeName": "清华大学",
    "graduateYear": "2015",
    "id": "1",
    "name": "张三",
    "sex": 1
  },
  "msg": "success"
}</span>
