问题内容

当我尝试序列化具有自引用关系的 dto 类 (nodeattributesdto) 时，我在 spring boot 应用程序中遇到 stackoverflowerror。该错误发生在执行dto类中的tostring方法期间。

nodeattributes.java：

// relevant parts of nodeattributes.java
@onetomany(mappedby = "parent")
@cache(usage = cacheconcurrencystrategy.read_write)
@jsonignoreproperties(value = { "children", "parent", "node" }, allowsetters = true)
private set<nodeattributes> children ;

@manytoone
@jsonignoreproperties(value = { "children", "parent", "node" }, allowsetters = true)
private nodeattributes parent;

// other fields, getters, setters, etc.

nodeattributesdto.java：

// relevant parts of nodeattributesdto.java
private set<nodeattributesdto> children;
private nodeattributesdto parent;

// getters, setters, and other methods...

@override
public string tostring() {
    return "nodeattributesdto{" +
        "id=" + getid() +
        // other fields...
        ", parent=" + getparent() +
        ", children=" + getchildren() +
        ", node=" + getnode() +
        "}";
