jersey spring tomcat 集成

期盼死亡的小丑

　　首先把jersey的相关jar放到WEB-INF/lib目录下
　　web.xml

<servlet>
<servlet-name>Jersey Spring</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>
<param-value>com.axisspring.api</param-value>//你的web service类所在的包
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Spring</servlet-name>
<url-pattern>/api/*</url-pattern>//你想匹配的路径
</servlet-mapping>
 　　application-context.xml

<context:annotation-config />
<context:component-scan base-package="com.axisspring.api" />
<bean id="apiDao" class="com.axisspring.dao.ApiDao">
</bean>
<bean id="apiService" class="com.axisspring.api.ApiService" >
</bean>
<bean id="apiService2" class="com.axisspring.api.ApiService2">
</bean>
<bean id="apiService3" class="com.axisspring.api.ApiService3">
</bean>
 　　ApiDao

public class ApiDao {
public String getName() {
return "mock";
}
}
　　ApiService

@Path("s1")
@Component
@Scope("request")
public class ApiService {
private int count;
@Autowired
private ApiDao apiDao;
@GET
@Produces(MediaType.APPLICATION_XML)
public List<City> getCity(@DefaultValue("shanghai") @QueryParam("cname") String cityName) {
count++;//这里虽然scope设置的是request，但实际上只有一个对象count会一直累加 ????
List<City> a = new ArrayList<City>();
for (int i = 0; i < 10; i++) {
City c = new City();
c.setName(cityName+ " " + i+" "+count);
c.setZone("zone " + i + apiDao.getName());
a.add(c);
}
return a;
}
 　　City

@XmlRootElement     //加上这个才能解析成json 或 xml
public class City {
private String name;
private String zone;
 　　ApiService2

@Path("s2")
@Component
@Scope("request")
public class ApiService2 {
@Autowired
private ApiDao apiDao;
@GET
@Produces(MediaType.APPLICATION_JSON)
public Person getCity(@DefaultValue("shanghai") @QueryParam("cname") String cityName) {
Person p = new Person();
p.setAge(22);
p.setName("lich");
City c = new City();
c.setName(cityName);
c.setZone("zone " + apiDao.getName());
p.setCity(c);
return p;
}
 　　输出
