spring-springMVC-MyBatis整合

Spring-SpringMVC-MyBatis整合

创建实体类：

 1 package com.neuedu.ssm.entity;
 2 
 3 public class Employee {
 4 
 5     private Integer id;
 6     private String lastName;
 7     private boolean gender;
 8     private String email;
 9     public Employee() {
10         super();
11         // TODO Auto-generated constructor stub
12     }
13     public Employee(Integer id, String lastName, boolean gender, String email) {
14         super();
15         this.id = id;
16         this.lastName = lastName;
17         this.gender = gender;
18         this.email = email;
19     }
20     public Integer getId() {
21         return id;
22     }
23     public void setId(Integer id) {
24         this.id = id;
25     }
26     public String getLastName() {
27         return lastName;
28     }
29     public void setLastName(String lastName) {
30         this.lastName = lastName;
31     }
32     public boolean isGender() {
33         return gender;
34     }
35     public void setGender(boolean gender) {
36         this.gender = gender;
37     }
38     public String getEmail() {
39         return email;
40     }
41     public void setEmail(String email) {
42         this.email = email;
43     }
44     @Override
45     public String toString() {
46         return "Employee [id=" + id + ", lastName=" + lastName + ", gender="
47                 + gender + ", email=" + email + "]";
48     }
49     
50     
51     
52 }

创建service层：

 1 package com.neuedu.ssm.service;
 2 
 3 import java.util.List;
 4 
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Service;
 7 
 8 import com.neuedu.ssm.entity.Employee;
 9 import com.neuedu.ssm.mapper.EmployeeMapper;
10 
11 @Service
12 public class EmployeeService {
13 
14     @Autowired
15     private EmployeeMapper mapper;
16     
17     public List<Employee> getList(){
18         
19         return mapper.getList();
20         
21     }
22 }

创建mapper接口：

 1 package com.neuedu.ssm.mapper;
 2 
 3 import java.util.List;
 4 
 5 import com.neuedu.ssm.entity.Employee;
 6 
 7 public interface EmployeeMapper {
 8 
 9     public List<Employee> getList();
10     
11     
12 }

创建controller层：

 1 package com.neuedu.ssm.controller;
 2 
 3 import java.util.List;
 4 import java.util.Map;
 5 
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 
10 import com.neuedu.ssm.entity.Employee;
11 import com.neuedu.ssm.service.EmployeeService;
12 
13 @Controller
14 public class EmployeeController {
15 
16     @Autowired
17     private EmployeeService service;
18     
19     @RequestMapping("/getList")
20     public String getList(Map<String, Object> map){
21         List<Employee> list = service.getList();
22         map.put("list", list);
23         for (Employee employee : list) {
24             System.out.println(employee);
25         }
26         return "success";
27     }
28 }

创建jdbc.properties文件：

1 jdbc.jdbcUrl=jdbc:mysql://localhost:3306/mybatis
2 jdbc.driverClass=com.mysql.jdbc.Driver
3 jdbc.user=root
4 jdbc.password=root

创建applicationContext.xml：
