在SpringMvc中配置RestEasy,需要以下步骤
1、通过maven导入restEasy所需要的jar包
2、在web.xml文件中添加相应的配置。
3、编写服务。
具体步骤:
1、通过maven导入restEasy所需要的jar包,找到pom.xml文件(我自己的项目是加入到了web下的pom.xml文件中),添加下列代码,引入相应的jar包
1 <!--resteasy相关jar包引入 --> 2 <dependency> 3 <groupId>org.jboss.resteasy</groupId> 4 <artifactId>resteasy-jaxrs</artifactId> 5 <version>3.0.7.Final</version> 6 </dependency> 7 <!-- Reasteasy 集成Spring g工具包--> 8 <dependency> 9 <groupId>org.jboss.resteasy</groupId> 10 <artifactId>resteasy-spring</artifactId> 11 <version>3.0.7.Final</version> 12 </dependency> 13 14 <dependency> 15 <groupId>org.jboss.resteasy</groupId> 16 <artifactId>resteasy-jackson2-provider</artifactId> 17 <version>3.0.7.Final</version> 18 </dependency> 19 20 <dependency> 21 <groupId>org.jboss.resteasy</groupId> 22 <artifactId>resteasy-jaxb-provider</artifactId> 23 <version>3.0.7.Final</version> 24 </dependency>
jar导入之后,会在External Libraries中显示导入的jar包,如果未显示,说明jar没有正常导出;
2、web.xml中对resteasy的配置
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:spring.xml</param-value> </context-param> <!--为resteasy指定JSR-RS服务,代表通过指定资源类的全路径名进行加载,有多个资源类可通过逗号分开 --> <context-param> <param-name>resteasy.resources</param-name> <param-value>org.hc.heaton.product.controller.AppResteasyTestController,org.hc.heaton.app.controller.AppDoLoginController</param-value> </context-param> <!--要指定resteasy服务的前缀,否则和spring mvc的url-pattern冲突 --> <context-param> <param-name>resteasy.servlet.mapping.prefix</param-name> <param-value>/appServer</param-value> </context-param> <!-- 防止发生java.beans.Introspector内存泄露,应将它配置在ContextLoaderListener的前面 --> <!-- 详细描述见http://blog.csdn.net/jadyer/article/details/11991457 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <listener> <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class> </listener> <listener> <listener-class>org.jboss.resteasy.plugins.spring.SpringContextLoaderListener</listener-class> </listener> <!--<!– 实例化Spring容器 –>--> <!--<!– 应用启动时,该监听器被执行,它会读取Spring相关配置文件,其默认会到WEB-INF中查找applicationContext.xml –> --> <!--<listener>--> <!--<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>--> <!--</listener> --> <filter> <filter-name>encodingFilter</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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/views/city/*</url-pattern> </filter-mapping> <!-- 配置Shiro过滤器,先让Shiro过滤系统接收到的请求 --> <!-- 这里filter-name必须对应applicationContext.xml中定义的<bean id="shiroFilter"/> --> <!-- 使用[/*]匹配所有请求,保证所有的可控请求都经过Shiro的过滤 --> <!-- 通常会将此filter-mapping放置到最前面(即其他filter-mapping前面),以保证它是过滤器链中第一个起作用的 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 --> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置分页过滤器 --> <!-- 使用[/*]匹配所有请求,保证所有的可控请求都经过Shiro的过滤 --> <!-- 通常会将此filter-mapping放置到最前面(即其他filter-mapping前面),以保证它是过滤器链中第一个起作用的 --> <filter> <filter-name>PageFilter</filter-name> <filter-class>org.workholic.framework.common.ligeruiUtils.ServerPageFilter</filter-class> </filter> <filter-mapping> <filter-name>PageFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- SpringMVC核心分发器--> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--<param-value>/WEB-INF/classes/spring-mvc.xml</param-value>--> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--resteasy服务配置 --> <servlet> <servlet-name>resteasy</servlet-name> <servlet-class> org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher </servlet-class> <load-on-startup>2</load-on-startup> </servlet> <!--resteasy访问路径映射 --> <servlet-mapping> <servlet-name>resteasy</servlet-name> <url-pattern>/appServer/*</url-pattern> </servlet-mapping> <error-page> <error-code>500</error-code> <location>/errorpage.jsp</location> </error-page> <error-page> <error-code>404</error-code> <location>/errorpage.jsp</location> </error-page> <welcome-file-list> <welcome-file>/login.jsp</welcome-file> </welcome-file-list> </web-app>
3、编写服务
package org.hc.heaton.app.controller; import com.fasterxml.jackson.core.JsonParseException; import com.fasterxml.jackson.databind.ObjectMapper; import org.hc.heaton.app.service.AppDoLoginService; import org.hc.heaton.system.member.entity.ResultEntity; import org.springframework.beans.factory.annotation.Autowired; import org.workholic.framework.common.utils.UtilsJson; import javax.ws.rs.*; import javax.ws.rs.core.MediaType; import java.util.HashMap; import java.util.Map; /** * Created by py on 2016/10/26. * Description:App登录接口 */ @Path("/rest") public class AppDoLoginController { @Autowired AppDoLoginService appDoLoginService; /** * 接口登录 * @param cookie sid值(唯一标示) * @param postData 格式:{"username":"001","password":"dfdfd"} * @return */ @POST @Path("/doLogin") @Consumes({MediaType.APPLICATION_JSON}) //接口接受到的参数类型 @Produces({MediaType.APPLICATION_JSON + ";charset=UTF-8"}) //接口返回格式为json,返回编码格式为utf-8(解决中文乱码问题) public String doLogin(@HeaderParam("cookie") String cookie,String postData){ ResultEntity resultEntity=new ResultEntity(); Map<String,Object> postMap=null; if(!cookie.equals("") && !postData.equals("")){ postMap= UtilsJson.toMap(postData);//将Json转换成Map resultEntity=appDoLoginService.doLogin(postMap,cookie); } else { resultEntity.setSuccess(false); resultEntity.setMessage("用户名和密码不能为空,cookie值不能为空"); } String mess=UtilsJson.toJson(resultEntity); return mess; } }
特别说明:
@HeaderParam("cookie") String cookie参数可以获得请求头中的Cookie信息(Sid编码)
String postData参数传过来是Json格式的字符串,可以转换;如果参数是个实体类型,那resteasy可以自动转换
通过搜狐浏览器中的HttpRequester可以测试接口
