- @JsonProperty注解主要用于实体类的属性上，作用可以简单的理解为在反序列化的时候给属性重命名(多一个名字来识别)
- 代码示例
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;
/**

@Data
public class TestJson {
@JsonProperty("my_name")
private String myName;
@JsonProperty("my_age")
private Integer myAge;
}
import com.example.demojson.TestJson;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;
/**

@ApiOperation("测试@JsonProperty")
public TestJson testJson(@RequestBody TestJson testJson) {
String myName = testJson.getMyName();
Integer myAge = testJson.getMyAge();
System.out.println(testJson.toString());

}
}
