springboot LocalDateTime 序列化、反序列化全局配置

LocalDateTime按照自定义的格式进行序列化、反序列化

#

***********************

示例

**************

pojo 层

Order

@Data
public class Order {
    private String orderId;
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime orderTime;
    private Double price;
    private Integer amount;
}

**************

config 层

WebConfig

@Configuration
public class WebConfig {
    @Bean
    public ObjectMapper initObjectMapper(){
        ObjectMapper objectMapper=new ObjectMapper();
        JavaTimeModule javaTimeModule=new JavaTimeModule();
        javaTimeModule.addDeserializer(LocalDateTime.class,new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
        javaTimeModule.addSerializer(LocalDateTime.class,new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
                       //localDateTime按照 "yyyy-MM-dd HH:mm:ss"的格式进行序列化、反序列化
        objectMapper.registerModule(javaTimeModule);
        return objectMapper;
    }
}

**************

controller 层

HelloController

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public LocalDateTime hello(@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") LocalDateTime localDateTime){
        System.out.println("hello ==> "+localDateTime);
        return localDateTime;
    }
    @RequestMapping("/hello2")
    public Order hello2(Order order){
        System.out.println("hello2 ==> "+order);
        return order;
    }
    @RequestMapping("/hello3")
    public Order hello3(@RequestBody Order order){
        System.out.println("hello3 ==> "+order);
        return order;
    }
}

***********************

使用测试

*****************

/hello

localhost:8080/hello?localDateTime=2020-08-06 09:08:06

设置全局配置输出：2020-08-09 08:06:09

#控制台输出
hello ==> 2020-08-09T08:06:09

不设置全局配置输出：2020-08-09T08:06:09

*****************

/hello2

localhost:8080/hello2?orderId=1&orderTime=2020-08-06 08:06:09&price=2&amount=8

设置全局配置输出

             ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70][]
#控制台输出
hello2 ==> Order(orderId=1, orderTime=2020-08-06T08:06:09, price=2.0, amount=8)

不设置全局配置输出

            ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70 1][]

*****************

/hello3

localhost:8080/hello3，

header：Content-Type application/json

body：

{
    "orderId": "2",
    "orderTime": "2020-08-09 08:06:09",
    "price": "2",
    "amount": "8"
}

设置全局配置输出

            ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70 2][]
#控制台输出
hello3 ==> Order(orderId=1, orderTime=2020-08-09T08:06:09, price=2.0, amount=8)

不设置全局配置，无法反序列化，可在LocalDateTime加注解@JsonFormat(pattern = “yyyy-MM-dd HHss”)

            ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70 3][]
