当有这个接口时：

Map<String, List<Role>>时报如下问题：

这里要使用Adapter进行处理：

接口换成：

@WebService
    public interface MyService {
    
        public String say(String str);
    
        @XmlJavaTypeAdapter(MapAdapter.class)
        public Map<String, List<Role>> getRoles();
    }

实现为：

@WebService
    public class MyServiceImpl implements MyService {
    
    
        public String say(String str) {
    
            return "Hello" + str;
        }
    
        public Map<String, List<Role>> getRoles() {
    
            Map<String, List<Role>> map = new HashMap<String, List<Role>>();
            List<Role> roleList1 = new ArrayList<Role>();
            roleList1.add(new Role(1, "架构师"));
            roleList1.add(new Role(2, "技术总监"));
            map.put("xxx", roleList1);
    
            List<Role> roleList2 = new ArrayList<Role>();
            roleList2.add(new Role(3, "程序员"));
            map.put("yyy", roleList2);
    
            return map;
        }
    }

其中MapAdapter.java

public class MapAdapter extends XmlAdapter<MyRole[], Map<String, List<Role>>> {
    
        /***
         * 适配器转换 MyRole[] -> Map<String, List<Role>>
         * @param v
         * @return
         * @throws Exception
         */
        public Map<String, List<Role>> unmarshal(MyRole[] v) throws Exception {
    
            Map<String, List<Role>> map = new HashMap<String, List<Role>>();
    
            for(int i = 0; i < v.length; i++){
    
                MyRole r = v[i];
                map.put(r.getKey(), r.getValue());
            }
    
            return map;
        }
    
    
        /***
         * 适配器转换 Map<String, List<Role>> -> MyRole[]
         * @param v
         * @return
         * @throws Exception
         */
        public MyRole[] marshal(Map<String, List<Role>> v) throws Exception {
    
            MyRole[] roles = new MyRole[v.size()];
            int i = 0;
            for(String key : v.keySet()){
    
                roles[i] = new MyRole();
                roles[i].setKey(key);
                roles[i].setValue(v.get(key));
            }
    
            return roles;
        }
    }

MyRole.java

public class MyRole {
    
        private String key;
        private List<Role> value;
    
        public String getKey() {
            return key;
        }
    
        public void setKey(String key) {
            this.key = key;
        }
    
        public List<Role> getValue() {
            return value;
        }
    
        public void setValue(List<Role> value) {
            this.value = value;
        }
    }

Role.java

public class Role {
    
        private Integer id;
        private String roleName;
    
        public Role(){
    
        }
    
        public Role(Integer id, String roleName) {
            this.id = id;
            this.roleName = roleName;
        }
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getRoleName() {
            return roleName;
        }
    
        public void setRoleName(String roleName) {
            this.roleName = roleName;
        }
    }

User.java

public class User {
    
        private Integer id;
        private String userName;
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    }
