动态修改log4j日志级别

• 设置包的日志等级

Level level = Level.toLevel(Level.DEBUG);Logger logger = LogManager.getLogger(“package”);logger.setLevel(level);

• 设置全局日志等级

Level level = Level.toLevel(Level.DEBUG);LogManager.getRootLogger().setLevel(level);

• http控制

@Path("/conf")@Component("configurationResource")public class ConfigurationResource {    @GET    @Produces(MediaType.APPLICATION_XML)    @Path("/log/package/{package}/{level}")    public Response index(@PathParam("package") String p, @PathParam("level") String l) {        Level level = Level.toLevel(l);        Logger logger = LogManager.getLogger(p);        logger.setLevel(level);        return Response.ok().build();    }    @GET    @Produces(MediaType.APPLICATION_XML)    @Path("/log/root/{level}")    public Response index(@PathParam("level") String l) {        Level level = Level.toLevel(l);        LogManager.getRootLogger().setLevel(level);        return Response.ok().build();    }}
