ok,框架搭建完成,可以啓動一下看看是否正常，當然配置文件中掃描的包必須創建好

因爲上面配置了mapper掃描的xml，但是目前還沒有xml，所有會報錯。註釋掉就不會報錯了

2.mybatis逆向生成實體映射等.

init.properties

 #Mybatis Generator configuration
 project = E:/eclipse/workspace/zto-ssm/src/main/java
 #classPath=D:/maven/Reposeitory/com/oracle/ojdbc6/11.2.0.3.0/ojdbc6-11.2.0.3.0.jar
 classPath = D:/repository/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jar
 jdbc_driver = com.mysql.jdbc.Driver
 jdbc_url = jdbc:mysql://127.0.0.1:3306/mybatis
 jdbc_user = root
 jdbc_password = 123456

GeneratorConfig.xml

 <?xml version="1.0" encoding="UTF-8" ?>
 <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
 <generatorConfiguration>
     <!-- 引入配置文件 -->
     <properties resource="init.properties"/>

     <!-- 指定數據連接驅動jar地址 -->
     <classPathEntry location="${classPath}" />

     <!-- 一個數據庫一個context -->
     <context id="infoGuardian">
         <!-- 註釋 -->
         <commentGenerator >
             <property name="suppressAllComments" value="true"/><!-- 是否取消註釋 -->
         </commentGenerator>

         <!-- jdbc連接 -->
         <jdbcConnection driverClass="${jdbc_driver}"
             connectionURL="${jdbc_url}" userId="${jdbc_user}"
             password="${jdbc_password}" />

         <!-- 類型轉換 -->
         <javaTypeResolver>
             <!-- 是否使用bigDecimal， false可自動轉化以下類型（Long, Integer, Short, etc.） -->
             <property name="forceBigDecimals" value="false"/>
         </javaTypeResolver>

         <!-- 生成實體類地址 -->
         <javaModelGenerator targetPackage="cn.xyc.ssm.pojo"
             targetProject="${project}" >
             <!-- 是否在當前路徑下新加一層schema,eg：fase路徑com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] -->
             <property name="enableSubPackages" value="false"/>
             <!-- 是否針對string類型的字段在set的時候進行trim調用 -->
             <property name="trimStrings" value="true"/>
         </javaModelGenerator>

         <!-- 生成mapxml文件 -->
         <sqlMapGenerator targetPackage="cn.xyc.ssm.mapper"
             targetProject="${project}" >
             <!-- 是否在當前路徑下新加一層schema,eg：fase路徑com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] -->
             <property name="enableSubPackages" value="false" />
         </sqlMapGenerator>

         <!-- 生成mapxml對應client，也就是接口dao -->
         <javaClientGenerator targetPackage="cn.xyc.ssm.mapper"
             targetProject="${project}" type="XMLMAPPER" >
             <!-- 是否在當前路徑下新加一層schema,eg：fase路徑com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] -->
             <property name="enableSubPackages" value="false" />
         </javaClientGenerator>

         <!-- 配置表信息 -->
         <table schema="" tableName="user"
             domainObjectName="User" enableCountByExample="true"
             enableDeleteByExample="true" enableSelectByExample="true"
             enableUpdateByExample="true" selectByExampleQueryId="true">
             <!-- schema即爲數據庫名 tableName爲對應的數據庫表 domainObjectName是要生成的實體類 enable*ByExample
                 是否生成 example類   -->
             <!-- 忽略列，不生成bean 字段
             <ignoreColumn column="CLASS" />-->
             <!-- 指定列的java數據類型
             <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />-->
         </table>
     </context>
 </generatorConfiguration>

pom文件中必須加上相關插件，上面已經有了.

運行maven命令： mybatis-generator:generate 會生成相關文件，將映射文件移動到mybatis/mappers下面

3.Junit測試SSM框架

先添加日誌

log4j.properties

 log4j.rootLogger=DEBUG,A1
 log4j.logger.org.mybatis = DEBUG
 log4j.appender.A1=org.apache.log4j.ConsoleAppender
 log4j.appender.A1.layout=org.apache.log4j.PatternLayout
 log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n

TestSSM.java

 package cn.xyc.ssm;

 import java.util.List;

 import org.junit.Before;
 import org.junit.Test;
 import org.junit.runner.RunWith;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.context.ApplicationContext;
 import org.springframework.context.support.ClassPathXmlApplicationContext;
 import org.springframework.test.context.ContextConfiguration;
 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 import cn.xyc.ssm.mapper.UserMapper;
 import cn.xyc.ssm.pojo.User;


 /**
  *
  * @ClassName:  TestMyBatis
  * @Description: 測試ssm框架
  * @author: xyc
  * @date:   2017年2月13日 下午7:53:09
  *
  */
 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = { "classpath:spring/*.xml" })
 public class TestSSM {

     @Autowired
     private UserMapper userMapper;

     /**
      * @throws Exception
      */
     @Before
     public void setUp() throws Exception {
         // 初始化SPring容器
         //ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml",
         //        "applicationContext-mybatis.xml");
         // 從容器中獲取SqlSessionFactory
         // SqlSessionFactory sqlSessionFactory =
         // applicationContext.getBean(SqlSessionFactory.class);

         // SqlSession sqlSession = sqlSessionFactory.openSession(true);
         // this.userMapper = sqlSession.getMapper(UserMapper.class);
         //this.userMapper = applicationContext.getBean(UserMapper.class);
     }


     @Test
     public void test1() {

         List<User> queryAll = userMapper.queryAll();
         for (User user : queryAll) {
             System.out.println(user);
         }
     }
 }

結果：

4.EasyUI

導入jquery-easyui-1.2.6類庫就可以直接使用easyUI了

commons.js

 // 自定義的校驗器
 $.extend($.fn.validatebox.defaults.rules, {
     midLength : {
         validator : function(value, param) {
             return value.length >= param[0] && value.length <= param[1];
         },
         message : ''
     },
     equalLength : {
         validator : function(value, param) {
             return value.length == param[0];
         },
         message : '密碼必須爲4個字符!'
     }
 });

 $.extend($.fn.datagrid.defaults.editors, {
     datetimebox : {
         init : function(container, options) {
             var box = $('<input />').appendTo(container);
             box.datetimebox(options);
             return box;
         },
         getValue : function(target) {
             return $(target).datetimebox('getValue');
         },
         setValue : function(target, value) {
             $(target).datetimebox('setValue', value);
         },
         resize : function(target, width) {
             var box = $(target);
             box.datetimebox('resize', width);
         },
         destroy : function(target) {
             $(target).datetimebox('destroy');
         }
     }
 });
