Annotation | 作用 | 说明 |
@GET | 查询请求 | 相当于数据库的查询数据操作 |
@POST | 插入请求 | 相当于数据库的插入数据操作 |
@PUT | 更新请求 | 相当于数据库的更新数据操作 |
@DELETE | 删除请求 | 相当于数据的删除数据操作 |
@Path | uri路径 | 定义资源的访问路径,client通过这个路径访问资源。比如:@Path("user") |
@Produces | 指定返回MIME格式 | 资源按照那种数据格式返回,可取的值有:MediaType.APPLICATION_XXX。比如:@Produces(MediaType.APPLICATION_XML) |
@Consumes | 接受指定的MIME格式 | 只有符合这个参数设置的请求再能访问到这个资源。比如@Consumes("application/x-www-form-urlencoded") |
@PathParam | uri路径参数 | 写在方法的参数中,获得请求路径参数。比如:@PathParam("username") String userName |
@QueryParam | uri路径请求参数 | 写在方法的参数中,获得请求路径附带的参数。比如:@QueryParam("desc") String desc |
@DefaultValue | 设置@QueryParam参数的默认值 | 如果@QueryParam没有接收到值,就使用默认值。比如:@DefaultValue("description") @QueryParam("desc") String desc |
@FormParam | form传递的参数 | 接受form传递过来的参数。比如:@FormParam("name") String userName |
@BeanParam | 通过Bena的形式传递参数 | 接受client传递的bean类型的参数,同时这个bean可以在属性上配置@FormParam用以解决client的属性名称和bean的属性名称不一致的问题。比如:@BeanParam User user |
@Context | 获得一些系统环境信息 | 通过@Context可以获得以下信息:UriInfo、ServletConfig、ServletContext、HttpServletRequest、HttpServletResponse和HttpHeaders等 |
@XmlRootElement | 将bean转换为xml | 如果要讲bean以xml或json的格式返回,必须要这个注解。比如: @XmlRootElement public class User{...} |
