ApplicationContext를 언급하는 Spring Boot 애플리케이션이 즉시 종료됩니다.

1. 질문(문제점):

언급 한 유일한 오류는 ApplicationContext를 시작하는 동안 오류가 발생했다는 것입니다.

다음은 관련 코드 및 출력입니다.

TodoListApplication.java

    package com.foobar.TodoList;

    import java.util.ArrayList;
    import java.util.List;

    import com.foobar.TodoList.model.User;
    import com.foobar.TodoList.model.User.TodoItem;

    public class TodoListApplication implements CommandLineRunner {

참고 : pom 파일의 Java 버전은 11이라고 말하지만 jdk 15가 있지만 중요하다고 생각하지 않습니다.

주 2 : 내가 한 debug=true에 application.properties실제로 그것을 시작되지 않습니다, 단지 더 자세한 출력

2. 해결방안:

문제는 다음과 같습니다.

Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.isanoui.TodoList.model.User$TodoItem
    at org.hibernate.engine.internal.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:347) ~[hibernate-core-5.4.25.Final.jar:5.4.25.Final]
 ForeignKeys.java

OneToMany 또는 ManyToOne을 모두에게 계단식으로 만들 수 있습니다.

// @Column(name = "todos")
    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "user_id")
    private List<TodoItem> todos = new ArrayList<TodoItem>();

또는 어노테이션에 설명 된대로 먼저 내부 개체를 저장 한 다음 외부 개체를 저장할 수 있습니다.

public void run(String... args) throws Exception {

    TodoItem item = new TodoItem("mow the lawn", false);
    this.itemRepository.save(item); 

    List<TodoItem> todoItems = new ArrayList<TodoItem>();
    todoItems.add(item);
    this.userRepository.save(new User("Joe", "password", todoItems));
}
