Jersey在spring环境下的实现
目前项目用到Jersey 在这里记录一下
项目采用maven管理
1：pom.xml引得jersey相关jar
<dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-core</artifactId> <version>1.11</version> </dependency> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-server</artifactId> <version>1.11</version> </dependency> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-client</artifactId> <version>1.11</version> </dependency> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-json</artifactId> <version>1.10</version> </dependency> <dependency> <groupId>javax.ws.rs</groupId> <artifactId>jsr311-api</artifactId> <version>1.1.1</version> </dependency>
<dependency> <groupId>asm</groupId> <artifactId>asm</artifactId> <version>3.2</version> </dependency>
<dependency> <groupId>com.sun.jersey.contribs</groupId> <artifactId>jersey-spring</artifactId> <version>1.11</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </exclusion> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </exclusion> </exclusions> </dependency>
2:web.xml
<context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:spring/*.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <listener> <listener-class> org.springframework.web.context.request.RequestContextListener </listener-class> </listener> <servlet> <servlet-name>JerseyServlet</servlet-name> <servlet-class> com.sun.jersey.spi.spring.container.servlet.SpringServlet </servlet-class> <init-param> <param-name> com.sun.jersey.config.property.packages </param-name> <!-- 系统启动时扫描的包的路径--> <param-value>com.gissecur.mcas.webservices</param-value> </init-param> <init-param> <param-name> com.sun.jersey.api.json.POJOMappingFeature </param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>JerseyServlet</servlet-name> <url-pattern>/resources/*</url-pattern> </servlet-mapping>
3：要生成rest的service类
