除了@Ruben提供的上述说明之外,我想补充一点,您还可以在Spring RESTFull实现中引用相同的内容。
JAX-RS规范@PathParam-将URI模板参数的值或包含模板参数的路径段绑定到资源方法参数,资源类字段或资源类bean属性。
@Path("/users/{username}")
public class UserResource {
@GET
@Produces("text/xml")
public String getUser(@PathParam("username") String userName) {
...
}
}
@QueryParam-将HTTP查询参数的值绑定到资源方法参数,资源类字段或资源类bean属性。
URI:users / query?from = 100
@Path("/users")
public class UserService {
@GET
@Path("/query")
public Response getUsers(
@QueryParam("from") int from){
}}
要使用Spring实现相同的功能,可以使用
@PathVariable(Spring)== @PathParam(Jersey,JAX-RS),
@RequestParam(Spring)== @QueryParam(泽西岛,JAX-RS)
@javax.ws.rs.QueryParam
This annotation allows you to extract values from URI query parameters.
@javax.ws.rs.PathParam
This annotation allows you to extract values from URI template parameters.
PART-1 : @javax.ws.rs.PathParam
@Path("/mercedes")
public class MercedesService {
@GET
@Path("/e55/{year}")
@Produces("image/jpeg")
public Jpeg getE55Picture(@PathParam("year") String year) {
...
}
If I query the JAX-RS service with GET /mercedes/e55/2006, the getE55Picture()
method would match the incoming request and would be invoked.
PART-2 : @javax.ws.rs.QueryParam
URI might look like this: GET /cus?start=0&size=10
@Path("/cus")
public class GreedCorruption {
@GET
@Produces("application/xml")
public String getDeathReport(@QueryParam("start") int start,
@QueryParam("size") int size) {
...
}
}
