篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了6spring注解+springMVC注解+Mybatis注解+log4j+idea+maven相关的知识，希望对你有一定的参考价值。
1、项目结构如下
2、编辑pom.xml文件配置依赖

pom.xml
3、在java目录下的com.pojo包下创建Scott.java持久化类
1 package com.pojo;
2
3 import org.springframework.stereotype.Component;
4
5 import java.io.Serializable;
6
7 /**
8 * 多方引用一方对象
9 */
10 @Component
11 public class Scott implements Serializable
12 //多方所需字段
13 private Integer empno ;
14 private String ename ;
15 private Double sal ;
16 private Integer deptno;
17 //一方所需字段
18 private String dname;
19
20 public Scott()
21
22
23 public Scott(Integer empno, String ename, Double sal, Integer deptno, String dname)
24 this.empno = empno;
25 this.ename = ename;
26 this.sal = sal;
27 this.deptno = deptno;
28 this.dname = dname;
29
30
31 public Integer getEmpno()
32 return empno;
33
34
35 public void setEmpno(Integer empno)
36 this.empno = empno;
37
38
39 public String getEname()
40 return ename;
41
42
43 public void setEname(String ename)
44 this.ename = ename;
45
46
47 public Double getSal()
48 return sal;
49
50
51 public void setSal(Double sal)
52 this.sal = sal;
53
54
55 public Integer getDeptno()
56 return deptno;
57
58
59 public void setDeptno(Integer deptno)
60 this.deptno = deptno;
61
62
63 public String getDname()
64 return dname;
65
66
67 public void setDname(String dname)
68 this.dname = dname;
69
70
71 @Override
72 public String toString()
73 return "Scott" +
74 "empno=" + empno +
75 ", ename=" + ename + \\ +
76 ", sal=" + sal +
77 ", deptno=" + deptno +
78 ", dname=" + dname + \\ +
79 ;
80
81
Scott.java
4、在java目录下的com.mapper包下创建ScottMapper.java映射接口
1 package com.mapper;
2 import com.pojo.Scott;
3 import org.apache.ibatis.annotations.Delete;
4 import org.apache.ibatis.annotations.Insert;
5 import org.apache.ibatis.annotations.Select;
6 import org.apache.ibatis.annotations.Update;
7 import org.springframework.stereotype.Repository;
8
9 import java.util.List;
10 @Repository
11 public interface ScottMapper
12 @Select("select * from dept")
13 List<Scott> selectOneList();
14
15 @Select("select d.dname,e.* from dept d,emp e where e.deptno=d.deptno")
16 List<Scott> selectAll();
17
18 @Select("select d.dname,e.* from dept d,emp e where e.deptno=d.deptno and e.empno=#primaryKey")
19 Scott selectPrimaryKey(Integer primaryKey);
20
21 @Select("select d.dname,e.* from dept d,emp e where e.deptno=d.deptno and e.deptno=#foreignKey")
22 List<Scott> selectForeign(Integer foreignKey);
23
24 @Insert("insert into emp(empno,ename,sal,deptno) values(#empno,#ename,#sal,#deptno)")
25 int insertScott(Scott scott);
26
27 @Update("update emp set ename=#ename,sal=#sal,deptno=#deptno where empno=#empno")
28 int updateScott(Scott scott);
29
30 @Delete("delete from emp where empno=#primaryKey")
31 int deleteScott(Integer primaryKey);
32
ScottMapper.java
5、在java目录下的com.service包下创建业务层接口和实现类
1 package com.service;
2
3 import com.pojo.Scott;
4
5 import java.util.List;
6
7 public interface ScottService
8 List<Scott> downOption();
9 List<Scott> show();
10 Scott info(Integer primaryKey);
11 List<Scott> optionCondition(Integer foreignKey);
12 int add(Scott emp);
13 int edit(Scott emp);
14 int del(Integer primaryKey);
15
ScottService.java
1 package com.service;
2 import com.mapper.ScottMapper;
3 import com.pojo.Scott;
4 import org.springframework.beans.factory.annotation.Autowired;
5 import org.springframework.stereotype.Service;
6 import org.springframework.transaction.annotation.Transactional;
7
8 import java.util.List;
9 /*
10 @Service的功能等同于代理对象在spring的xml文件中动态添加bean节点,
11 如果不指定名称，则底层代理在构建bean节点的时候id是类的第一个首字母小写
12 <bean id="empServiceImpl" class="com.service.EmpServiceImpl"/>
13 @Service(value = "empse")的功能等同于代理对象在spring的xml文件中动态添加id值为empse的bean节点
14 <bean id="empse" class="com.service.EmpServiceImpl"/>
15 */
16 @Service
17 @Transactional
18 public class ScottServiceImpl implements ScottService
19 /*
20 @Autowired是spring的资源包下注解，按照对象的类型进行自动注入，
21 和对象名称无关，只要类型是匹配的，代理就会在你需要的时候给你注入对象值
22 @Resource是javax包下的注解，按照对象属性名进行注入，
23 和对象名称关系密切，如果对象名称不匹配，则不能完成注入，会报错
24 总结：相比而言，使用@Resource的出错记录更大，因此我们常规选择使用@Autowired
25 */
26 @Autowired
27 private ScottMapper scottMapper;
28
29 @Override
30 public List<Scott> downOption()
31 return scottMapper.selectOneList();
32
33
34 @Override
35 public List<Scott> show()
36 return scottMapper.selectAll();
37
38
39 @Override
40 public Scott info(Integer primaryKey)
41 return scottMapper.selectPrimaryKey(primaryKey);
42
43
44 @Override
45 public List<Scott> optionCondition(Integer foreignKey)
46 return scottMapper.selectForeign(foreignKey);
47
48
49 @Override
50 public int del(Integer primaryKey)
51 return scottMapper.deleteScott(primaryKey);
52
53
54 @Override
55 public int add(Scott scott)
56 return scottMapper.insertScott(scott);
57
58
59 @Override
60 public int edit(Scott scott)
61 return scottMapper.updateScott(scott);
62
63
ScottServiceImpl.java
6、在java目录下的com.controller包下创建控制类CenterController.java
1 package com.controller;
2 import com.pojo.Scott;
3 import com.service.ScottService;
4 import org.springframework.beans.factory.annotation.Autowired;
5 import org.springframework.stereotype.Controller;
6 import org.springframework.ui.Model;
7 import org.springframework.web.bind.annotation.RequestMapping;
8 import org.springframework.web.bind.annotation.ResponseBody;
9
10 import javax.servlet.http.HttpSession;
11 import java.util.HashMap;
12 import java.util.List;
13 import java.util.Map;
14 @Controller
15 public class CenterController
16 @Autowired
17 private ScottService scottService;
18
19 @RequestMapping("/option.do")
20 public String optionData(HttpSession session)
21 List<Scott> deptlist=scottService.downOption();
22 session.setAttribute("deptlist",deptlist);
23 return "redirect:/main.jsp";
24
25
26 @RequestMapping("/show.do")
27 @ResponseBody
28 public Map<String,Object> showData(Integer foreignKey)
29 Map<String,Object> map=new HashMap<String,Object>();
30 List<Scott> emplist=null;
31 //根据部门编号条件查询
32 if(foreignKey!=-1)
33 emplist=scottService.optionCondition(foreignKey);
34 else //查询所有
35 emplist=scottService.show();
36
37 map.put("emplist",emplist);
38 return map;
39
40
41
42 @RequestMapping("/info.do")
43 public String info(Integer primaryKey, Model model)
44 Scott emp=scottService.info(primaryKey);
45 model.addAttribute("emp2",emp);
46 return "/edit.jsp";
47
48
49
50 @RequestMapping("/edit.do")
51 public String edit(Scott emp)
52 //根据主键编号查询只有一条数据
53 System.out.println(scottService.edit(emp)>0?"edit success":"edit fail");;
54 //使用重定向跳转
55 return "redirect:/main.jsp";
56
57
58 @RequestMapping("/add.do")
59 public String add(Scott emp)
60 //根据主键编号查询只有一条数据
61 System.out.println(scottService.add(emp)>0?"add success":"add fail");;
62 //使用重定向跳转
63 return "redirect:/main.jsp";
64
65
66 @RequestMapping("/del.do")
67 public String del(Integer primaryKey)
68 //根据主键编号查询只有一条数据
69 System.out.println(scottService.del(primaryKey)>0?"del success":"del fail");;
70 //使用重定向跳转
71 return "redirect:/main.jsp";
72
73
CenterController.java
7、在resouces目录下创建log4j.properties日志文件
1 log4j.rootLogger=DEBUG, Console
2 #Console
3 log4j.appender.Console=org.apache.log4j.ConsoleAppender
4 log4j.appender.Console.layout=org.apache.log4j.PatternLayout
5 log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
6
7 log4j.logger.org.apache=INFO
8 log4j.logger.java.sql.ResultSet=INFO
9 log4j.logger.java.sql.Connection=DEBUG
10 log4j.logger.java.sql.Statement=DEBUG
11
log4j.properties
8、在webapp目录下的WEB-INF文件夹下创建springmvc-servlet.xml核心配置文件，和web.xml文件
1 <?xml version="1.0" encoding="UTF-8"?>

web.xml
10、在webapp目录下创建js目录，且将jquery的库文件jquery-1.8.3.js拷贝进去
11、在webapp目录下创建main.jsp文件
1 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
2 <%@ page contentType="text/html;charset=UTF-8" language="java" %>

main.jsp
12、在webapp目录的js目录下创建show.js文件
1 $(function ()
