使用的是spring,spring mvc,mybatis框架,然后用generatorConfig.xml生成的,所以实体还有dao里面包括映射是一样的我就不发那块的代码了,controller是自己做的,三表级联,代码如下

 1 package com.charmyin.cmstudio.njfu.eat_name.controller;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.bind.annotation.ResponseBody;
11 
12 import com.charmyin.cmstudio.njfu.eat_name.persistence.Eat_nameMapper;
13 import com.charmyin.cmstudio.njfu.eat_name.vo.Eat_name;
14 import com.charmyin.cmstudio.njfu.eat_name.vo.Eat_nameExample;
15 
16 @Controller
17 @RequestMapping("/eat")
18 public class Eat_nameController {
19 
20     @Resource
21     Eat_nameMapper eat_nameMapper;
22     
23     @RequestMapping(value="/index")
24     public String Index(){
25         return "/njfu/eat/index";
26     }
27     
28     @RequestMapping(method=RequestMethod.POST,value="/name")
29     @ResponseBody
30     public List<Eat_name> getall(){
31         Eat_nameExample enamee=new Eat_nameExample();
32         List<Eat_name> list=eat_nameMapper.selectByExample(enamee);
33         return list;
34     }
35 }

这是第一个表的controller

 1 package com.charmyin.cmstudio.njfu.eat_address.controller;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.bind.annotation.ResponseBody;
11 
12 import com.charmyin.cmstudio.njfu.eat_address.persistence.Eat_addressMapper;
13 import com.charmyin.cmstudio.njfu.eat_address.vo.Eat_address;
14 import com.charmyin.cmstudio.njfu.eat_address.vo.Eat_addressExample;
15 
16 @Controller
17 @RequestMapping("/eatadd")
18 public class Eat_addressController {
19 
20     @Resource
21     Eat_addressMapper eat_addressMapper;
22     
23     @RequestMapping(method=RequestMethod.POST,value="/address")
24     @ResponseBody
25     public List<Eat_address> getadd(String tid){
26         Eat_addressExample eaddresse=new Eat_addressExample();
27         eaddresse.or().andTidEqualTo(tid);
28         List<Eat_address> list=eat_addressMapper.selectByExample(eaddresse);
29         return list;
30     }
31 }

这是第二个表的controller

 1 package com.charmyin.cmstudio.njfu.eat_price.controller;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.bind.annotation.ResponseBody;
11 
12 import com.charmyin.cmstudio.njfu.eat_price.persistence.Eat_priceMapper;
13 import com.charmyin.cmstudio.njfu.eat_price.vo.Eat_price;
14 import com.charmyin.cmstudio.njfu.eat_price.vo.Eat_priceExample;
15 
16 @Controller
17 @RequestMapping("/eatp")
18 public class Eat_priceController {
19 
20     @Resource
21     Eat_priceMapper eat_priceMapper;
22     
23     @RequestMapping(method=RequestMethod.POST,value="/price")
24     @ResponseBody
25     public List<Eat_price> getprice(String uid){
26         Eat_priceExample epricee=new Eat_priceExample();
27         epricee.or().andUidEqualTo(uid);
28         List<Eat_price> list=eat_priceMapper.selectByExample(epricee);
29         return list;
30     }
31 }

第三个

接下来是它指向的jsp

 1 <%@ page language="java" contentType="text/html; charset=utf-8"
 2     pageEncoding="utf-8"%>
 3 <%@ taglib uri="/WEB-INF/tlds/cmstudio.tld" prefix="cmstudio"%>

 5 <!DOCTYPE html>
 6 <html>
 7 <head>
 8 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 9 <title>${application_name_cn}</title>
10 
11 
12 <cmstudio:htmlBase />
13 
14 <!--Start importing the jquery files -->
15 <cmstudio:importJsCss name="jquery" version="${jquery_version}" />
16 <!--End import the jquery files -->
17 <!--Start importing the jeasyui files -->
18 <cmstudio:importJsCss name="jeasyui" version="${jeasyui_version}" />
19 </head>
20 <body>
21     <input id="test1" class="easyui-combobox"
22         data-options="

28             panelHeight:'auto',
29             onSelect:function(rec){
30                 var id=rec.id;
31                 $('#test2').combobox('clear');
32                 $('#test2').combobox('reload','eatadd/adddress?tid='+id);
33             }
34         ">
35     <input id="test2" class="easyui-combobox"
36         data-options="

53     
54     $('#test3').combobox({
55         valueField:'id',
56         textField:'price',
57         method:'post',
