json中@JsonProperty注解详解说明

设置jackson的maven依赖

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.5.3</version>
</dependency>

import com.fasterxml.jackson.annotation.JsonProperty;
public class User { 
    @JsonProperty("name") 
    private String userName; 
   
    public String getUserName() { 
        return userName; 
    } 
   
    public void setUserName(String userName) { 
        this.userName = userName; 
    } 
}  


----测试程序-----
import com.fasterxml.jackson.core.JsonProcessingException; 
import com.fasterxml.jackson.databind.ObjectMapper; 
public class Main { 
    public static void main(String[] args) throws JsonProcessingException { 
        User user = new User(); 
             user.setUserName("java265.com---"); 
        System.out.println(new ObjectMapper().writeValueAsString(user)); 
    } 
}
