Spring MVC是通过DispatcherServlet来加载Spring配置文件的,因此不需要在web.xml中配置ContextLoaderListener。但是CXF却需要通过ContextLoaderListener来加载Spring。

这样就产生了一个矛盾,如果不配置ContextLoaderListener,CXF就无法正常使用。但如果配置ContextLoaderListener,又会造成Spring的重复加载(DispatcherServlet一次,ContextLoaderListener一次)

在网上查了一下资料,只看到一个国外的程序员提出不配置ContextLoaderListener,通过写一个CXFController,来替代默认的CXFServlet。但是这种HACK的方式总是不太好

所以我采用一种折中的方式,来解决Spring MVC和cxf并存的问题。但是也不是很优雅,希望有人能给出更好的办法

首先是web.xml的配置

在ContextLoaderListener里面,加载cxf和spring的公共配置信息。然后在DispatcherServlet中加载spring mvc所需的信息。利用Spring配置文件拆分的方式,既实现spring mvc和cxf的共存,又避免spring配置信息的重复加载

然后是公共的配置信息,beans.xml

然后是cxf所需的信息,cxf.xml

这顺便还带来一个附带的好处,即进行单元测试的时候,可以仅加载必须的类,比如做DAO组件的单元测试,就不需要加载spring-mvc.xml和cxf.xml了

@RunWith(SpringJUnit4ClassRunner.class) 
 @ContextConfiguration(locations = { "file:WebContent/WEB-INF/beans.xml" }) 
 public class UserDaoHibernateTest { 
 @Autowired 
 private UserDao dao; 
 private static String ID; 
 @Test 
 public void testInsert() { 
 User user = new User(); 
 user.setName("fme001"); 
 user.setAge(23); 
 dao.insert(user); 
 @Test 
 public void testQueryByName() { 
 String name = "fme001"; 
 User user = dao.queryByName(name); 
 assertEquals(23, user.getAge()); 
 ID = user.getId(); 
 @Test 
 public void testQueryByAge() { 
 int age = 23; 
 List<User> result = dao.queryByAge(age); 
 assertEquals(1, result.size()); 
 @Test 
 public void testQueryAll() { 
 List<User> result = dao.queryAll(); 
 assertEquals(1, result.size()); 
 @Test 
 public void testQuery() { 
 User user = dao.query(ID); 
 assertEquals(23, user.getAge()); 
 assertEquals("fme001", user.getName()); 
 @Test 
 public void testUpdate() { 
 User user = dao.query(ID); 
 user.setAge(24); 
 dao.update(user); 
 user = dao.query(ID); 
 assertEquals(24, user.getAge()); 
 @Test 
 public void testDelete() { 
 User user = dao.query(ID); 
 dao.delete(user); 
 }



可以看到,集成cxf和spring mvc确实不算很方便,需要绕一绕。上述方法只是一个折中的方案,希望新版本的cxf可以提供一个CXFController,这样的话就可以统一用DispatcherServlet来加载Spring,不配置ContextLoaderListener。这样的话web.xml可以简洁很多。或者如果哪位网友有更好的方式,请指教一下
