Caused by: com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptionsjava.util.List是接口, 而 JAXB 无法处理接口。 ???this problem is related to the following location: ???????at java.util.List ???????at private java.util.Map com.rg2.webservice.jaxws_asm.GetrolesResponse._return ???????at com.rg2.webservice.jaxws_asm.GetrolesResponse
在cxf处理map类型的时候需要在接口上加注解，否则会报以上错误。
@WebServicepublic interface HelloWorld { ???public String say(String str); ???????public List<Role> getRoleByUser(User user); ???????/** ????* 获取所有用户对应的角色 ????* @return ????*/ ???@XmlJavaTypeAdapter(MapAdapter.class) ???public Map<String, List<Role>> getroles();}其中MapAdapter单独写

没有报错,打开浏览器
如之前写的那样，将客户端使用wsdl2自动生成代码
然后通过Client类调用服务端接口
package com.rg2.webservice;import java.util.List;public class Client { ???public static void main(String[] args) { ???????HelloWorldService service = new HelloWorldService(); ???????HelloWorld helloWorldPort = service.getHelloWorldPort(); ???????MyRoleArray getroles = helloWorldPort.getroles(); ???????List<MyRole> roleList = getroles.item; ???????for (int i = 0; i < roleList.size(); i++) { ???????????MyRole my = roleList.get(i); ???????????System.out.print(my.key + ":"); ???????????for (Role role : my.value) { ???????????????System.out.print(role.getId()+","+role.getRoleName()); ???????????} ???????????System.out.println("==============="); ???????} ???}}运行结果为：
