SpringMVC注解之@JsonView

SpringMVC注解之@JsonView

使用步骤：

第一步：使用接口来声明多个视图

第二步：在值对象的get方法上指定视图

第三步：在Controller方法上指定视图

import java.util.Date;

import javax.validation.constraints.Past;

import com.fasterxml.jackson.annotation.JsonView;

public class User {
	
	public interface UserSimpleView {};
	public interface UserDetailView extends UserSimpleView {};
	
	private String id;
	
	private String username;

	private String password;

	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;
	}
	
}

Controller

	@GetMapping
	@JsonView(User.UserSimpleView.class)
	public List<User> query(UserQueryCondition condition,
			@PageableDefault(page = 2, size = 17, sort = \"username,asc\") Pageable pageable) {
		System.out.println(ReflectionToStringBuilder.toString(condition, ToStringStyle.MULTI_LINE_STYLE));

		System.out.println(pageable.getPageSize());
		System.out.println(pageable.getPageNumber());
		System.out.println(pageable.getSort());

		List<User> users = new ArrayList<>();
		users.add(new User());
		users.add(new User());
		users.add(new User());
		return users;
	}

	@GetMapping(\"/{id:\\\\d+}\")
	@JsonView(User.UserDetailView.class)
	public User getInfo(@ApiParam(\"用户id\") @PathVariable String id) {
//		throw new RuntimeException(\"user not exist\");
		System.out.println(\"进入getInfo服务\");
		User user = new User();
		user.setUsername(\"tom\");
		return user;
	}

结果是根据指定视图输出指定的内容
