CXF原生支持Spring,可以和Spring無縫集成。WebService框架CXF實戰一在Tomcat中發佈WebService(二)通過Spring Web實現CXFServlet。下面將Spring和CXF集成在一起,CXF發佈的WebService可以調用Spring的Bean。
創建Maven Web項目,在pom.xml中添加CXF和Spring的引用,由於該Web項目中不涉及數據庫,沒有添加Spring JDBC、Spring ORM等數據庫相關模塊。

在項目中添加Dao接口及實現類,WebService調用Dao層數據,項目結構如圖所示。
HelloDao接口,提供welcome方法。
package com.rvho.cxfserver.dao;
public interface HelloDao {
String welcome(String name);
}
HelloDao接口實現類HelloDaoImpl
package com.rvho.cxfserver.dao.impl;
import org.springframework.stereotype.Repository;
import com.rvho.cxfserver.dao.HelloDao;
@Repository("helloDao")
public class HelloDaoImpl implements HelloDao {
@Override
public String welcome(String name) {
return "歡迎使用CXF!" + name;
}
}
HelloWS接口,由於集成了Spring,該接口既是WebService,也是Spring Service。
package com.rvho.cxfserver.ws;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
@WebService(
name = "HelloWS",
targetNamespace = "http://www.tmp.com/services/hello"
)
public interface HelloWS {
@WebMethod
String welcome(@WebParam(name = "name") String name);
}
HelloWS接口實現類HelloWSImpl,實現類調用HelloDaoImpl的方法。
package com.rvho.cxfserver.ws.impl;
import javax.annotation.Resource;
import javax.jws.WebService;
import org.springframework.stereotype.Service;
import com.rvho.cxfserver.dao.HelloDao;
import com.rvho.cxfserver.ws.HelloWS;
@WebService(
endpointInterface = "com.rvho.cxfserver.ws.HelloWS",
portName = "HelloWSPort",
serviceName = "HelloWSService",
targetNamespace = "http://www.tmp.com/services/hello"
)
@Service("helloWS")
public class HelloWSImpl implements HelloWS {
@Resource
private HelloDao helloDao;
@Override
public String welcome(String name) {
return helloDao.welcome(name);
}
}
Spring上下文配置

在WEB-INF下創建cxf-servlet.xml,內容如下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- helloWS通過註解獲取 -->
<jaxws:endpoint id="helloWSEndpoint" implementor="#helloWS" address="/hello"></jaxws:endpoint>
</beans>
在web.xml中添加Spring上下文Listener以及CXFServlet
<?xml version="1.0" encoding="UTF-8"?>
