persistence.xml位于构建路径中的src/META-INF中，因此应该可以正确地找到它。有谁有什么想法吗？

我通常将persistence.xml放在资源文件夹/src/main/resouces/META-INF/persistence.xml中，因为我确实记得构建过程中的问题，没有将资源复制到输出目录。

我刚刚看了一下我们的配置，它看起来有点不同：

</bean>

希望这能有所帮助:-)

将persistence.xml放在资源文件夹中/src/main/resouces/META-INF/persistence.xml为我提供此解决方案

如果您有一个hibernate映射类与另一个非映射类有关系，则可能会发生此错误，解决方案是将关系项检查为@瞬态(hibernate将忽略它，仅使用它来检查这是否是错误，并在稍后映射相关类)。示例：

代码语言：javascript
复制
@Entity
public class City {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;

private String name;

@Transient
private State state;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public State getState() {
    return state;
}

public void setState(State state) {
    this.state = state;
}

}

这是可能产生错误的非映射类：

代码语言：javascript
复制
public class State {

private String name;

}
