二 启动类
package org.fkit.springboottest;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App
{
public static void main( String[] args )
{
SpringApplication.run(App.class, args);
}
}三 持久化类
package org.fkit.springboottest.bean;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="tb_student")
public class Student implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name ;
private String address ;
private int age ;
private char sex;
public Student() {
}
public Student(String name, String address, int age, char sex) {
super();
this.name = name;
this.address = address;
this.age = age;
this.sex = sex;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public char getSex() {
return sex;
}
public void setSex(char sex) {
this.sex = sex;
}
}四 控制器
package org.fkit.springboottest.controller;
import java.util.HashMap;
import java.util.Map;
import javax.annotation.Resource;
import org.fkit.springboottest.bean.Student;
import org.fkit.springboottest.service.SchoolService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/student")
public class StudentController {
@Resource
private SchoolService shcoolService;
@PostMapping(value="/save")
public Map save(@RequestBody Student stu) {
shcoolService.save(stu);
Map params = new HashMap<>();
params.put("code", "success");
return params;
}
/**
* 获取学生信息
* @param id
*/
@GetMapping(value="/get/{id}")
@ResponseBody
public Student qryStu(@PathVariable(value = "id") Integer id){
Student stu = shcoolService.selectByKey(id);
return stu;
}
} 五 service
package org.fkit.springboottest.service;
import java.util.Optional;
import javax.annotation.Resource;
import org.fkit.springboottest.bean.Student;
import org.fkit.springboottest.repository.StudentRepository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
public class SchoolService {
// 定义数据访问层接口对象
@Resource
private StudentRepository studentRepository;
@Transactional
public void save(Student stu) {
studentRepository.save(stu);
}
public Student selectByKey(Integer id) {
Optional op = studentRepository.findById(id);
return op.get();
}
} 六 Repository
package org.fkit.springboottest.repository;
import org.fkit.springboottest.bean.Student;
import org.springframework.data.jpa.repository.JpaRepository;
public interface StudentRepository extends JpaRepository {
} 七 测试
1 控制器测试
package org.fkit.springboottest;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = App.class)
public class StudentControllerTest {
// 注入Spring容器
@Autowired
private WebApplicationContext wac;
// MockMvc实现了对Http请求的模拟
private MockMvc mvc;
@Before
public void setupMockMvc(){
// 初始化MockMvc对象
mvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
/**
* 新增学生测试用例
* @throws Exception
*/
@Test
public void addStudent() throws Exception{
String json="{\"name\":\"孙悟空\",\"address\":\"花果山\",\"age\":\"700\",\"sex\":\"男\"}";
mvc.perform(MockMvcRequestBuilders.post("/student/save")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.accept(MediaType.APPLICATION_JSON_UTF8)
.content(json.getBytes()) //传json参数
)
.andExpect(MockMvcResultMatchers.status().isOk())
.andDo(MockMvcResultHandlers.print());
}
/**
* 获取学生信息测试用例
* @throws Exception
*/
@Test
public void qryStudent() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/student/get/1")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.accept(MediaType.APPLICATION_JSON_UTF8)
)
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.name").value("孙悟空"))
.andExpect(MockMvcResultMatchers.jsonPath("$.address").value("花果山"))
.andDo(MockMvcResultHandlers.print());
}
}2 service测试
package org.fkit.springboottest;
import org.fkit.springboottest.bean.Student;
import org.fkit.springboottest.service.SchoolService;
import org.hamcrest.CoreMatchers;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
public class StudentServiceTest {
// 注入Service
@Autowired
private SchoolService studentService;
@Test
public void findOne() throws Exception {
Student stu = studentService.selectByKey(1);
Assert.assertThat(stu.getName(),CoreMatchers.is("孙悟空"));
}
