Springmvc返回JSON以及日期處理

1.demo-base中pom.xml有此三個

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson.version}</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
</dependency>

 

2.UserDTO定義

public class UserDTO implements Serializable {
    private Long id;
    private String name;
    private Date birthday;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @JsonFormat(pattern = "yyyy-MM-dd")
    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

@JsonFormat:表示json對日期格式化配置

 

3.DemoController

package com.company.controller;

import com.company.dto.UserDTO;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.Date;


/**
 * @RestController
 */
@Controller
@RequestMapping("demo")
public class DemoController {
    private static final Logger LOG= LoggerFactory.getLogger(DemoController.class);

    @RequestMapping("sayHello")
    @ResponseBody
    public String sayHello(String name){
        LOG.info("前置參數name=>{}",name);
        return "Hello,"+name+"!";
    }

    @RequestMapping("getUser")
    @ResponseBody
    public UserDTO getUser(@DateTimeFormat(pattern = "yyyy-MM-dd")Date birthday){
        UserDTO userDTO = new UserDTO();
        userDTO.setId(10000000L);
        userDTO.setName("ss");
        userDTO.setBirthday(birthday);
        return userDTO;
    }
}

@DateTimeFormat爲Springmvc框架中對應的日期格式轉換。
