Lombok - @Builder 인스턴스 생성 불가능

@Builder
public class Test<T> {
    private T a;
    private String b;
    private String c;

    public static Test tt (Object responseData) {
        return CommonResponse.builder()
                .responseData(responseData)
                .b("호롤록")
                .c("호로로롥").build();
    }
}

    @GetMapping("/test")
    public Mono<Test> test() {
        return Mono.just(Test.tt("안녕안녕 test"));
    }

 

Test code 실행시 아래와 같은 에러 남

org.springframework.core.codec.CodecException: Type definition error: [simple type, class sb_admin.common.response.CommonResponse]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of sb_admin.common.response.CommonResponse (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator) at [Source: (org.springframework.core.io.buffer.DefaultDataBuffer$DefaultDataBufferInputStream); line: 1, column: 2] at org.springframework.http.codec.json.AbstractJackson2Decoder.processException(AbstractJackson2Decoder.java:211) Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException: Error has been observed at the following site(s): |_ checkpoint ⇢ Body from GET /test [DefaultClientResponse]

 

no Creators, like default constructor, exist => 생성자 없다는 뜻임

@Builder
@Getter
@NoArgsConstructor
public class Test<T> {
    private T a;
    private String b;
    private String c;

    public static Test tt (Object responseData) {
        return CommonResponse.builder()
                .responseData(responseData)
                .b("호롤록")
                .c("호로로롥").build();
    }
}

 

생성자를 붙였지만 추가적인 에러가 남

Error:(9, 1) java: constructor CommonResponse in class sb_admin.common.response.CommonResponse cannot be applied to given types; required: no arguments found: T,java.lang.String,sb_admin.common.response.CommonState reason: actual and formal argument lists differ in length

 

@AllArgsConstructor 붙여서 에러 해결
