它提到的唯一错误是启动applicationcontext时出错。
以下是相关代码和输出：
todolistapplication.java文件

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;
    import com.foobar.TodoList.repository.UserRepository;

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

    @SpringBootApplication
    public class TodoListApplication implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(TodoListApplication.class, args);
    }

    @Autowired
    private UserRepository userRepository;

    @Override
    public void run(String... args) throws Exception {
        List<TodoItem> todoItems = new ArrayList<TodoItem>();
        todoItems.add(new TodoItem("mow the lawn", false));

        this.userRepository.save(new User("Joe", "password", todoItems));
    }
}

注意：pom文件中的java版本是11，但我有jdk15，但我认为这并不重要
注2：我做到了 debug=true 在 application.properties 但实际上并没有启动它，只是更详细的输出

问题如下

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

你可以使一个单间或多个单间级联到所有人

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

或者您可以按照comment中的描述，先保存内部对象，然后保存外部对象。

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));
}

这可能是由于您要调用commandlinerunner造成的。我总是通过调用commandlinerunner bean来使用它。在你的情况下就是这样：

@Bean
    public CommandLineRunner prepopulateDB(UserRepository userRepository) {
        return args -> {
    List<TodoItem> todoItems = new ArrayList<TodoItem>();
    todoItems.add(new TodoItem("mow the lawn", false));

    userRepository.save(new User("Joe", "password", todoItems));
        };
    }

错误提示：

object references an unsaved transient instance - save the transient instance before flushing: com.isanoui.TodoList.model.User$TodoItem; nested exception is java.lang.IllegalStateException:

我猜你在user和todoitem之间有一个onetomany关系，它们之间的关系不正确，你从hibernate刷新会话，但在此之前你可以保存实体(我认为你应该纠正2个实体之间的关系，如果没有，可以纠正，再检查一下对象是如何工作的）
