User 类是model

service 是

@WebService
public interface IUserManager {


public java.util.List<java.lang.Object> getUserLists();

public Map getUserMap();
}


实现是
@javax.jws.WebService(serviceName =
"IUserManagerService",endpointInterface =
"org.mumu.user.service.IUserManager")
public class IUserManagerImpl implements IUserManager {

private static final Logger LOG =
Logger.getLogger(IUserManagerImpl.class
.getName());

private IBaseDao baseDao;

/*
* (non-Javadoc)
*
* @see org.mumu.user.service.IUserManager#getUserLists(*
*/

public java.util.List<java.lang.Object> getUserLists() {
LOG.info("Executing operation getUserLists");
try {

String sql = "select * from t_user";

System.out.println(sql);

List list = baseDao.getLists(sql, new UserRowMapper());

System.out.println(list.size());

return list;

} catch (Exception ex) {
ex.printStackTrace();
throw new RuntimeException(ex);
}
}

public Map getUserMap() {
String sql = "select * from t_user where user_id=1";
return baseDao.queryForMap(sql);
}

public class UserRowMapper implements ParameterizedRowMapper<User> {
public User mapRow(ResultSet rs, int rowNum) throws SQLException {
User user = new User();
user.setLoginName(rs.getString("LOGIN_NAME"));
user.setUserID(rs.getLong("USER_ID"));
user.setUserEmail(rs.getString("USER_EMAIL"));
user.setUserDate(rs.getDate("USER_DATE"));
user.setUserName(rs.getString("USER_NAME"));
user.setUserPassword(rs.getString("USER_PASSWORD"));
user.setAuthoritiesFromString(rs.getString("USER_AUTHORITY"));

return user;
}
}

public void setBaseDao(IBaseDao baseDao) {
this.baseDao = baseDao;
}

}

建议你把SEI (Service Endpoint Interface)好好改一下

public java.util.List<java.lang.Object> getUserLists();

public Map getUserMap();

这两个方法的返回参数都让JAXB 无从侍从。
要知道SEI 是帮你做Java Object 到 XML 以及 XML 到 Java Object 转换的基础。

如果是List的话，应该指定List中存放的数据类型。
如果是Map而且你是使用CXF的缺省data binding JAXB， 那你还需要写Adapter来完成。
如果你使用Agies binding 你可以直接使用Map [1]。

谢谢willem
public java.util.List<java.lang.Object> getUserLists();
改成
public java.util.List<User> getUserLists();

但如果我想List 里面存放的是两张关联的表的数据，不知道怎么写
比如
select a.*,b.* from a,b where a.id=b.id


通过spring jdbcTemplate回List （每张表没有对应的dao,）
public List getLists(String sql) {


return getJdbcTemplate().queryForList(sql);

}

我没用用过DAO， 建议你还是对jdbcTemplate 中返回的List进行处理后再交给CXF。
这样也比较安全。

JAXB 对待泛型还是有些问题的， 建议你使用extension 而不是泛型来定义你的更
新接口。

Hello Willem:

谢谢你的回复！我明白你说的意思，但是如何用extension来做我有些不明白？

对我来讲，CXF的JSon对象序列化机制实在是有些死板。我很想替换掉他的序列化机制，改用我自己的Interceptor来手工序列化对象。这样我可以不用写固定的annotation或者用复杂的data
binding tools来做，请问你再这方面有什么建议么？
我看到cxf-user forum里的Sergey
谈到WADL的support，我相信如果基于CXF-RS-*的开发，在以后也会转到用WADL来定义和构建。如果我想以后迁移到标准的开发方式来，现在是否依然需要保持CXF的原有序列化组件呢？
我同样发了个详细的帖子在cxf-user forum里面，包括详细的代码和实现。Link：

OH,
我试着看了下他的序列化实现。这个JAXRSOutInterceptor里面做的事情很多，我想简单用对象序列化的方法需要更多的代码实现，所以我放弃了。

原来的代码我试着用继承的方式来搞，虽然这样会产生很多的代码类在case by case情况下。但也想不到有更好的方法了：（

JAXB 的功能还是很强大的， 只要你定义好数据模型 ，case by case的工作很少的。

Hi Willem:

真的很感谢你的回复！我目前有些这方面的research对于CXF-RS的应用，你能提供些实际经验给我么？谢谢！

项目的一些介绍：主要是based在CXF-RS服务实现上的。前台view
layer使用静态富客户端（Extjs）来实现的，通过Ajax进行RS的访问，中间层采用JSON作为数据载体，整体用RESTful风格来实现和进行调用。业务层面上很简单，主要是实现一个配置管理的系统。没有过多的业务流程和操作，大部分的cases是进行CRUD的操作。

Thanks！
Sam

Hello Willem:

首先谢谢你的帮助，对于JAXB序列化确实有些困难和小问题。不过Sergey提供了一个小方案，来完美的支持泛型的序列化。我相信也有很多人如果用泛型的话会遇到类似的问题，请不妨参考这个帖子的讨论和解决方案。
