idea搭建ssm框架+easyui实现 增删改查功能

本文档详述了在IDEA中使用Spring、SpringMVC、Mybatis(SSM)框架结合EasyUI实现增删改查功能的过程。涉及到的配置包括web.xml、log4j.properties、mybatis-config.xml、spring-mvc.xml和applicationContext.xml等,并介绍了项目目录结构、关键类如UserController、UserDao、UserService及分页工具PageBean等的实现。文章还强调了Mybatis相对于Hibernate的轻量级特性,以及环境搭建过程中可能出现的jar包冲突问题。

spring版本:4.0.6

mybatis版本:3.2.5

1、项目目录结构

技术分享

其中,controller包下存放控制层文件,dao下存放各个model类相关的数据库操作接口,entity下放置各种model类,mappers下放置各个dao对应的映射文件,service服务层就不说了,放置各种service接口,impl是其具体实现类。

2、web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- Spring配置文件 -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <!-- 编码过滤器 -->
  <filter>
      <filter-name>encodingFilter</filter-name>
      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
      <async-supported>true</async-supported>
      <init-param>
          <param-name>encoding</param-name>
          <param-value>UTF-8</param-value>
      </init-param>
  </filter>
  <filter-mapping>
      <filter-name>encodingFilter</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  <!-- 配置Spring监听器 -->
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- 添加对SpringMVC的支持 -->
  <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-mvc.xml</param-value>
      </init-param>
  </servlet>
  <servlet-mapping>
      <servlet-name>SpringMVC</servlet-name>
      <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
</web-app>

 

3、log4j.properties配置日志

log4j.rootLogger=DEBUG, Console  
  
#Console  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  
  
log4j.logger.java.sql.ResultSet=INFO  
log4j.logger.org.apache=INFO  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG  

 

4、mybatis-config.xml配置

<?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>

    <!-- 别名 -->
    <typeAliases>
        <package name="com.java.entity" />    <!-- 后面书写类全名时默认加该包名前缀如:<resultMap type="User"... -->
    </typeAliases>

</configuration>

 

5、spring-mvc.xml配置

<?xml version="1.0" encoding="UTF-8"?>    
<beans xmlns="http://www.springframework.org/schema/beans"    
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">    
    
    <!-- 使用注解的包,包括子集 -->
    <context:component-scan base-package="com.java.controller"></context:component-scan>
    
    <!-- 视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>

    </bean>
</beans>
