wildfly 实践4 --SpringMvc 服务访问DAS服务
注：此web服务部署在50.253机器上，即与DAS服务分开部署
(转载请注明来源:cnblogs coder-fang)
- 与wildfly 实践3 一样，创建maven 工程,如图:
- 修改pom文件，如下:

- 在WEB-INF下创建相关配置文件,目录如下:
- web.xml配置如下:
View Code
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>ticket ui</display-name> <context-param> <param-name>webAppRootKey</param-name> <param-value>webapp.root</param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </context-param> <context-param> <param-name>spring.profiles.default</param-name> <param-value>production</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>restappServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>restappServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
- servlet-context.xml配置如下:
View Code
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "> <mvc:annotation-driven /> <context:component-scan base-package="com.ticket.controller" /> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" /> <bean id="defaultAnnotationHandlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> <bean id="annotationMethodHandlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter" /> <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter" /> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=utf-8</value> <value>text/xml</value> <value>text/plain</value> </list> </property> </bean> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </list> </property> </bean> <!-- 配置文件上传解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8" /> <property name="maxUploadSize" value="10485760" /> <property name="maxInMemorySize" value="40960" /> <!--resolveLazily属性启用是为了推迟文件解析，以便在UploadAction 中捕获文件大小异常--> <property name="resolveLazily" value="true"/> </bean> </beans>
- applicationContext.xml配置如下,此处为预留配置，还未加相关bean:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "> </beans>
- jboss-ejb-client.xml配置如下:
<jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0"> <client-context> <ejb-receivers> <remoting-ejb-receiver outbound-connection-ref="remote-ejb-connection"/> </ejb-receivers> </client-context> </jboss-ejb-client>
- 创建 com.ticket.controller.MainController,代码片段如下:
View Code
@Controller @RequestMapping(value = "/") public class MainControll{ private static final Logger logger = Logger.getLogger("MainControll"); private static Context ctx; private SiteManagerRemote siteRemote; @PostConstruct public void setup() throws NamingException{ try { MainControll.ctx = new InitialContext(); siteRemote = (SiteManagerRemote) ctx.lookup("ejb:/ticket-agency-db//SiteManager!com.sanjian.boundary.SiteManagerRemote"); } catch(Exception e){ }} @RequestMapping(value = "/show/{status}",method=RequestMethod.GET) @ResponseBody public Object showSeats(HttpSession session,@PathVariable int status) { HashMap<String, Object> ret = new HashMap<String, Object>(); try { QueryResult<Site> st = siteRemote.listSites(status); //siteRemote.saveSite(s,p); ret.put("data", st.getResultlist()); ret.put("total", st.getTotalrecord()); } catch (Exception e) { e.printStackTrace(); ret.put("error", e.getMessage()); } return ret; } }
- 运行Run->RunConfiguration,如图:
- 确保本机(50.253)中的wildfly 已运行，点击上图中的Run按钮。
- 成功的代码片段如下:

阶段总结：至此 WEB服务访问EJB服务的实践已完成，项目较大的话业务服务也可完全独立出SessionBean，如果同学们无法完成，则大部分可能的问题都是配置问题，分布式的业务服务大体流程即为如此，文笔不好，谅解。
