JAX-RS之resteasy跟spring整合
其实,在JAX-RS标准下,jboss的resteasy跟spring结合的话,无非是如何去取得
spring中的bean而已.两个方法,例子如下
1 比如有个接口和实现类
public interface CustomerBo{ String getMsg(); } 实现类
public class CustomerBoImpl implements CustomerBo { public String getMsg() { return "RESTEasy + Spring example"; }applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">
<bean id="customerBo" name="code">import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware; public class SpringApplicationContext implements ApplicationContextAware { private static ApplicationContext appContext; // Private constructor prevents instantiation from other classes private SpringApplicationContext() {} @Overridepublic void setApplicationContext(ApplicationContext applicationContext)throws BeansException {appContext = applicationContext; } public static Object getBean(String beanName) {return appContext.getBean(beanName);} }
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">
<bean name="code">import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.core.Response;import com.mkyong.context.SpringApplicationContext;import com.mkyong.customer.CustomerBo; @Path("/customer")public class PrintService { CustomerBo customerBo; @GET@Path("/print")public Response printMessage() { customerBo = (CustomerBo) SpringApplicationContext.getBean("customerBo"); String result = customerBo.getMsg(); return Response.status(200).entity(result).build(); } }
web.xml整合

</web-app> 1 楼 grassking 2012-01-04 resteasy中能通过@Autowrited注解来获取bean吗？ 2 楼 ruijin5566 2012-07-26 学习了，在项目里用了
