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

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

<?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>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>

<plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <!--调整分页合理化-->
            <property name="reasonable" value="true"/>
        </plugin>
    </plugins>
</configuration>

web.xml的配配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- springMVC -->
  <servlet>
  <servlet-name>dispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  <servlet-name>dispatcherServlet</servlet-name>
  <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

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）】

mybatis的****配置：MBG.xml

官网：http://www.mybatis.org/mybatis-3/

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

    </javaClientGenerator>

    <!--table指定每个表生成策略-->
     <table tableName="tbl_info" domainObjectName="TblInfo"></table>
  </context>

</generatorConfiguration>

****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;
