Javascript org.springframework.web.util.NestedServletException:处理程序调度失败；嵌套的异常是java.lang.StackOverflowerr

我不明白我所犯的这个错误，它已经变得非常令人沮丧。。。我试图使用DataTables来显示具有oneToMany关系的表中的数据，在视图中显示数据的唯一方法是将关系设置为null，这样上面的错误就会消失，但我不知道如何按需要显示数据。提前谢谢

在用户中：

@JoinColumn(name = "id_rol", referencedColumnName = "id_rol", foreignKey = @ForeignKey(name = "fk_di")) 
@ManyToOne(optional = false) 
private Rol rol;

如果有人对解决方案感兴趣：

我将此类添加到我的项目中，并更改了控制器的最后一行：

GsonBuilder gsonBuilder = new GsonBuilder();
new GraphAdapterBuilder().addType(User.class).registerOn(gsonBuilder);
Gson gson = gsonBuilder.create();
return gson;

这样我就得到了这个Json响应，以及所有需要的信息：

{"draw":"1","recordsFiltered":"3","recordsTotal":"3","data":[{"0x1":{"idUser":3,"username":"grtyg","name":"","lastname":"","totalRecords":3,"rol":{"idRol":2,"rol":"User ad"}}}}]}

我可以简单地在Rol实体中使用javax@Transient注释，如下所示：

 @Transient 
 @OneToMany(cascade = CascadeType.ALL, mappedBy = "rol")
 private Set<User> users;

@Transient
@OneToMany（cascade=CascadeType.ALL，mappedBy=“rol”）
私人用户；

但后来我需要使用它

GsonBuilder gsonBuilder = new GsonBuilder();
new GraphAdapterBuilder().addType(User.class).registerOn(gsonBuilder);
Gson gson = gsonBuilder.create();
return gson;

{"draw":"1","recordsFiltered":"3","recordsTotal":"3","data":[{"0x1":{"idUser":3,"username":"grtyg","name":"","lastname":"","totalRecords":3,"rol":{"idRol":2,"rol":"User ad"}}}}]}

 @Transient 
 @OneToMany(cascade = CascadeType.ALL, mappedBy = "rol")
 private Set<User> users;
