我正在尝试使用带有 @POST 注释的 RestEasy 将两个复杂对象作为参数传输。

@POST
@Path("/save")
@Consumes("application/json")
public void save(ComplexeObjectAleph objectAleph, ComplexeObjectBeth objectBeth);

只有一个参数是可以的，但有两个 - 我得到异常：

这是可能的，但要小心。

这两个参数必须用 注释@Form。

@Path("playarea")
public interface PlayareaRsInterface {

    @POST
    @Path("save")
    @Produces(MediaType.APPLICATION_JSON)
    public void save(@Form ComplexeObjectAleph objectAleph, @Form ComplexeObjectBeth objectBeth);

}

并且这两个类的属性必须有@FormParam(...)注解：

public class ComplexeObjectAleph {

    @FormParam("aleph")
    public String aleph;

}

public class ComplexeObjectBeth {

    @FormParam("beth")
    public String beth;

}

但要注意， 的值@FormParam(...)必须不相等，否则 RestEasy 无法正确解析数据。可能是 RestEasy 的错误。
