com.fasterxml.jackson.databind.JsonMappingException: No suitable constructor

java报错：com.fasterxml.jackson.databind.JsonMappingException: No suitable constructor

解决：加上static就好

参考：java - JsonMappingException: No suitable constructor found for type [simple type, class ]: can not instantiate from JSON object - Stack Overflow

示例代码：

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import lombok.Data;
import lombok.experimental.Accessors;import java.util.ArrayList;
import java.util.List;@JsonIgnoreProperties(ignoreUnknown = true)
@Data
@Accessors(chain = true)
public class QueryEniResponse {private String eniId;private String name;private String vpcId;private String subnetId;private String zoneName;private String description;private String createdTime;private String macAddress;private String status;private String networkInterfaceTrafficMode;private List<PrivateIpItem>  privateIpSet = new ArrayList<>();private List<String> securityGroupIds = new ArrayList<>();private List<String> enterpriseSecurityGroupIds = new ArrayList<>();@JsonIgnoreProperties(ignoreUnknown = true)@Data@Accessors(chain = true)public static class PrivateIpItem{private Boolean primary;private String privateIpAddress;private String publicIpAddress;}
}
