1.导入相关依赖
父工程的pom文件，用来集中管理版本

ok,框架搭建完成,可以启动一下看看是否正常，当然配置文件中扫描的包必须创建好
因为上面配置了mapper扫描的xml，但是目前还没有xml，所有会报错。注释掉就不会报错了
2.mybatis逆向生成实体映射等.
init.properties
#Mybatis Generator configurationproject = 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.jarclassPath = D:/repository/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jarjdbc_driver = com.mysql.jdbc.Driverjdbc_url = jdbc:mysql://127.0.0.1:3306/mybatisjdbc_user = rootjdbc_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"/><!-- 指定数据连接驱动jar地址 --><classPathEntry location="${classPath}" /><!-- 一个数据库一个context --><context id="infoGuardian"><!-- 注释 --><commentGenerator ><property name="suppressAllComments" value="true"/><!-- 是否取消注释 --></commentGenerator><!-- jdbc连接 --><jdbcConnection driverClass="${jdbc_driver}"connectionURL="${jdbc_url}" userId="${jdbc_user}"password="${jdbc_password}" /><!-- 类型转换 --><javaTypeResolver><!-- 是否使用bigDecimal， false可自动转化以下类型（Long, Integer, Short, etc.） --><property name="forceBigDecimals" value="false"/></javaTypeResolver><!-- 生成实体类地址 --><javaModelGenerator targetPackage="cn.xyc.ssm.pojo"targetProject="${project}" ><!-- 是否在当前路径下新加一层schema,eg：fase路径com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] --><property name="enableSubPackages" value="false"/><!-- 是否针对string类型的字段在set的时候进行trim调用 --><property name="trimStrings" value="true"/></javaModelGenerator><!-- 生成mapxml文件 --><sqlMapGenerator targetPackage="cn.xyc.ssm.mapper"targetProject="${project}" ><!-- 是否在当前路径下新加一层schema,eg：fase路径com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] --><property name="enableSubPackages" value="false" /></sqlMapGenerator><!-- 生成mapxml对应client，也就是接口dao --><javaClientGenerator targetPackage="cn.xyc.ssm.mapper"targetProject="${project}" type="XMLMAPPER" ><!-- 是否在当前路径下新加一层schema,eg：fase路径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即为数据库名 tableName为对应的数据库表 domainObjectName是要生成的实体类 enable*ByExample 是否生成 example类 --><!-- 忽略列，不生成bean 字段 <ignoreColumn column="CLASS" />--><!-- 指定列的java数据类型 <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />--></table></context></generatorConfiguration>pom文件中必须加上相关插件，上面已经有了.
运行maven命令：mybatis-generator:generate 会生成相关文件，将映射文件移动到mybatis/mappers下面
3.Junit测试SSM框架
先添加日志
log4j.properties
log4j.rootLogger=DEBUG,A1log4j.logger.org.mybatis = DEBUGlog4j.appender.A1=org.apache.log4j.ConsoleAppenderlog4j.appender.A1.layout=org.apache.log4j.PatternLayoutlog4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%nTestSSM.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: 测试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"); // 从容器中获取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); } }}结果：
4.EasyUI
导入jquery-easyui-1.2.6类库就可以直接使用easyUI了
commons.js
// 自定义的校验器$.extend($.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 : '密码必须为4个字符!'}});$.extend($.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');}}});index.jsp
