一：主要任务
1.说明
@RequestBody 映射请求体到java方法的参数
日期类型参数的处理
@Valid注解
BindingResult验证请求参数的合法性并处理校验结果
二：@RequestBody
1.@RequestBody
测试类
/**
* @throws Exception
*
*/
@Test
public void whenCreateSuccess() throws Exception {
String content="{\"username\":\"tom\",\"password\":null}";
mockMvc.perform(MockMvcRequestBuilders.post("/user")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(content))
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.id").value("1"));
}
User.java
package com.cao.dto;
import com.fasterxml.jackson.annotation.JsonView;
public class User {
//接口
public interface UserSimpleView {};
public interface UserDetailView extends UserSimpleView {}; //继承之后，可以展示父的所有
private String username;
private String password;
private String id;
@JsonView(UserSimpleView.class)
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@JsonView(UserDetailView.class)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@JsonView(UserSimpleView.class)
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}控制类
@JsonView(User.UserDetailView.class)
@PostMapping
public User create(@RequestBody User user){
System.out.println(user.getId());
System.out.println(user.getUsername());
System.out.println(user.getPassword()); user.setId("1");
return user;
}
三：日期类型的处理
1.说明
使用时间戳。
2.程序
User中添加Date类型字段
package com.cao.dto;
import java.util.Date;
import com.fasterxml.jackson.annotation.JsonView;
public class User {
//接口
public interface UserSimpleView {};
public interface UserDetailView extends UserSimpleView {}; //继承之后，可以展示父的所有
private String username;
private String password;
private String id;
private Date birthday;
@JsonView(UserSimpleView.class)
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@JsonView(UserDetailView.class)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@JsonView(UserSimpleView.class)
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@JsonView(UserSimpleView.class)
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}测试类
/**
* @throws Exception
* 测试请求的创建
*/
@Test
public void whenCreateSuccess() throws Exception {
Date date=new Date();
System.out.println(date.getTime());
String content="{\"username\":\"tom\",\"password\":null,\"birthday\":"+date.getTime()+"}";
String result=mockMvc.perform(MockMvcRequestBuilders.post("/user")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(content))
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.id").value("1"))
.andReturn().getResponse().getContentAsString();
System.out.println("result="+result);
}
控制类
@PostMapping
public User create(@RequestBody User user){
System.out.println(user.getId());
System.out.println(user.getUsername());
System.out.println(user.getPassword());
System.out.println(user.getBirthday()); user.setId("1");
return user;
}
效果：
四：@Valid
1.说明
只有满足校验的时候，才进行业务处理
2.校验的步骤
对字段进行校验要求
在服务上加@Valid
3.程序
User.java
package com.cao.dto;
import java.util.Date;
import org.hibernate.validator.constraints.NotBlank;
import com.fasterxml.jackson.annotation.JsonView;
public class User {
//接口
public interface UserSimpleView {};
public interface UserDetailView extends UserSimpleView {}; //继承之后，可以展示父的所有
private String username;
@NotBlank
private String password;
private String id;
private Date birthday;
@JsonView(UserSimpleView.class)
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@JsonView(UserDetailView.class)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@JsonView(UserSimpleView.class)
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@JsonView(UserSimpleView.class)
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}控制类
@PostMapping
public User create(@Valid @RequestBody User user){
System.out.println(user.getId());
System.out.println(user.getUsername());
System.out.println(user.getPassword());
System.out.println(user.getBirthday()); user.setId("1");
return user;
}
测试类
/**
* @throws Exception
* 测试请求的创建
*/
@Test
public void whenCreateSuccess() throws Exception {
Date date=new Date();
System.out.println(date.getTime());
String content="{\"username\":\"tom\",\"password\":null,\"birthday\":"+date.getTime()+"}";
String result=mockMvc.perform(MockMvcRequestBuilders.post("/user")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(content))
.andExpect(MockMvcResultMatchers.status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.id").value("1"))
.andReturn().getResponse().getContentAsString();
System.out.println("result="+result);
}
4.效果
5.BindingResult
在上面的程序中，校验没有通过，则请求不进入方法体，但是有时候还需要一些处理的
6.程序
控制类
@PostMapping
public User create(@Valid @RequestBody User user,BindingResult errors){
if(errors.hasErrors()) {
errors.getAllErrors().stream().forEach(error->System.out.println(error.getDefaultMessage()));
} System.out.println(user.getId());
System.out.println(user.getUsername());
System.out.println(user.getPassword());
System.out.println(user.getBirthday()); user.setId("1");
return user;
}

这里暂时都打印出来，个性化还需要在后面处理。
