我有一个问题,我有一个转换器类称为aConverter:
@XmlRootElement(name = "aConverter")
public class aConverter implements ConverterBase{
private A a;
private Set<B> bs;
/// some constructor code here
...
@XmlElement(name="B")
public Set<B> getBs() {
bs = a.getBs();
return bs;
}
public void setBs(Set<B> bs) {
a.setBs(bs);
}
}
A类和B类分别以循环方式定义:
public class A {
private Set <B> bs;
//constructor code here
...
public Set<B> getBs() {
return this.bs;
}
public void setBs(Set<B> bs) {
this.bs = bs;
}
}
&GT;
public class B {
private A a;
// some constructor code here
...
public A getA() {
return this.a;
}
public void setA(A a) {
this.a = a;
}
}
现在,当我在网络服务时,我看到以下错误:

我真的没有想法,任何对此的反馈都会非常好。
干杯!

在EclipseLink JAXB(MOXy)中,我们引入了@XmlInverseReference扩展来解决这个问题。有关如何在JAX-RS服务中使用它的示例,请查看:
