SSM整合小案例

SSM（Spring+SpringMVC+Mybatis）

    一、添加jar包

            ①直接添加

                目前整合所用到的jar包：

                        aspectjweaver-1.8.9.jar
        c3p0-0.9.1.jar
        commons-logging-1.2.jar
        jackson-annotations-2.8.0.jar
        jackson-core-2.8.8.jar
        jackson-databind-2.8.8.jar
        jsqlparser-0.9.5.jar
        jstl-1.2.jar
        mybatis-3.4.2.jar
        mybatis-generator-core-1.3.5.jar
        mybatis-spring-1.3.1.jar
        mysql-connector-java-5.1.41.jar
        pagehelper-5.0.0.jar
        spring-aop-4.3.7.RELEASE.jar
        spring-aspects-4.3.7.RELEASE.jar
        spring-beans-4.3.7.RELEASE.jar
        spring-context-4.3.7.RELEASE.jar
        spring-core-4.3.7.RELEASE.jar
        spring-expression-4.3.7.RELEASE.jar
        spring-jdbc-4.3.7.RELEASE.jar
        spring-tx-4.3.7.RELEASE.jar
        spring-web-4.3.7.RELEASE.jar

        spring-webmvc-4.3.7.RELEASE.jar

            ②Maven方式添加：pom.xml

                


com.github.pagehelper

org.mybatis.generator

二、配置文件

                数据库相关信息：dbconfig.properties

                        jdbc.driver=com.mysql.jdbc.Driver
                        jdbc.url=jdbc:mysql://192.168.233.128:3306/mybatis
                        jdbc.username=root
                        jdbc.password=*********

                        #jdbc.driver=oracle.jdbc.OracleDriver
                        #jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
                        #jdbc.username=scott

                        #jdbc.password=scott

               mybatis的配置文件：mybatis-config.xml

        

        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

        "http://mybatis.org/dtd/mybatis-3-config.dtd">

       

           

           

       

   

web.xml的配配置：

  mybatis_configure
 
    index.html
    index.jsp
 
 
  contextConfigLocation
  classpath:applicationContext.xml
 
 
  org.springframework.web.context.ContextLoaderListener
 
 
 
  dispatcherServlet
  org.springframework.web.servlet.DispatcherServlet
  1
 
 
  dispatcherServlet
  /
 

web.xml没有配置字符编码过滤器，需要自己添加

SpringMVC的配置：dispatcherServlet-servlet.xml

【注：当wen.xml不指定springmvc配置文件位置的时候，可以用这种方式来进行配置（servlet名-servlet.xml）】

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

spring的配置文件：applicationContext.xml

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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">

mybatis的逆向工程配置：MBG.xml

官网：http://www.mybatis.org/mybatis-3/

  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

 
 
               
           
 
            connectionURL="jdbc:mysql://192.168.233.128:3306/mybatis"
        userId="root"
        password="koonisession97">
   

   
     
   

        targetProject=".\src">
     
     
   

        targetProject=".\conf">
     
   

          targetProject=".\src">
     
   

   
     

 

逆向工程代码：TestMBG.java

官网：http://www.mybatis.org/generator

package com.hz.mybatis.test;

import java.io.File;
import java.util.ArrayList;
import java.util.List;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

public class TestMBG {
public static void main(String[] args) throws Exception {
  List warnings = new ArrayList();
   boolean overwrite = true;
   File configFile = new File("mybatis-generator.xml");
   ConfigurationParser cp = new ConfigurationParser(warnings);
   Configuration config = cp.parseConfiguration(configFile);
   DefaultShellCallback callback = new DefaultShellCallback(overwrite);
   MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
   myBatisGenerator.generate(null);
}

}

到此配置文件就编写完成，接下来进行测试：

JSP页面：

效果：

点击：显示数据

点击：清除数据
