스프링부트와 자바 버전은 위와 같다.

Querydsl 수정을 하고, 실행 후!

호출을 했는데, 에러가 떴다.

 

 

postman에서는 500에러가 떴다.

 

참고: https://laughcryrepeat.tistory.com/136

검색을 하닥 위 블로그를 참고하여 해결했다.

 

Spring Boot 3.x 버전에서는 2.x 버전과는 다르게 설정을 해줘야 한다고 한다.

정말 설정이 어려운 Querydsl...

 

 

 

👉 QuyryDslConfiguration.java 변경 전

package com.example.querydsltest.config;

import com.querydsl.jpa.impl.JPAQueryFactory;
import jakarta.persistence.EntityManager;
import jakarta.persistence.PersistenceContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class QueryDslConfiguration {

    @PersistenceContext
    private EntityManager entityManager;

    @Bean
    public JPAQueryFactory jpaQueryFactory() {

        return new JPAQueryFactory(entityManager);
    }
}

 

 

 

👉 QuyryDslConfiguration.java 변경 후

package com.example.querydsltest.config;

import com.querydsl.jpa.JPQLTemplates;
import com.querydsl.jpa.impl.JPAQueryFactory;
import jakarta.persistence.EntityManager;
import jakarta.persistence.PersistenceContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class QueryDslConfiguration {

    @PersistenceContext
    private EntityManager entityManager;

    @Bean
    public JPAQueryFactory jpaQueryFactory() {

        return new JPAQueryFactory(JPQLTemplates.DEFAULT,entityManager);
    }
}

`JPQLTemplates.DEFCAULT`를 추가한 후에 다시 호출해본다.
