Java Jersey框架的最佳實踐，讓你的RESTful API更出色

@Path("/users")
public class UserResource {

@GET
@Produces(MediaType.APPLICATioN_JSON)
public List<User> getAllUsers() {
return userService.getAllUsers();
}

@POST
@Consumes(MediaType.APPLICATION_jsON)
public User createUser(User user) {
return userService.createUser(user);
}

@PUT
@Path("/{id}")
@Consumes(MediaType.APPLICATION_JSON)
public User updateUser(@PathParam("id") Long id, User user) {
return userService.updateUser(id, user);
}

@DELETE
@Path("/{id}")
public void deleteUser(@PathParam("id") Long id) {
userService.deleteUser(id);
}
}

public class LoggingFilter implements Filter {

@Override
public void doFilter(FilterChain chain, Request request, Response response) throws IOException, ServletException {
long startTime = System.currentTimeMillis();
chain.doFilter(request, response);
long endTime = System.currentTimeMillis();
logger.info("Request {} {} took {} ms", request.getMethod(), request.getPath(), endTime - startTime);
}
}

public class UserResourceConfig extends ResourceConfig {

public UserResourceConfig() {
reGISter(UserResource.class);
register(LoggingFilter.class);
}
}

public class UserResource {

@Inject
private UserService userService;

@GET
@Produces(MediaType.APPLICATION_JSON)
public List<User> getAllUsers() {
return userService.getAllUsers();

}
