slf4j-spring-boot-starter - 减少编写日志的组件
软件简介
一个注解搞定日志的组件,减少到处编写日志的烦恼,还可定位代码哟
软件架构
依赖spring-boot-starter-aop
原理说明
AOP + Reflect
作用范围
任意由 spring 调用的方法
当前版本
1.2.0 (已提交中央仓库)
安装教程
mvn clean install
使用说明
一、准备工作
-
添加依赖:
wiki.xsx
slf4j-spring-boot-starter
1.2.0
-
开启日志:
yml方式:
logging:
level:
wiki.xsx.core: 对应级别
properties方式:
**logging.level.wiki.xsx.core** =对应级别
二、开始使用(使用DEBUG模式)
@ParamLog注解示例:
-
日志注解标记:
@RestController
public class TestParamLogController {@ParamLog(value = "ParamLog-test1") @GetMapping("/paramLogTest1") **public** **Map** < **String** , **Object** > **logTest1** ( **HttpServletRequest** request, **Map** < **String** , **Object** > param) { **Map** < **String** , **Object** > result = **new** **HashMap** <>(3); result.put("code", 200); result.put("msg", "success"); result.put("data", param); **return** result; } @ParamLog(value = "ParamLog-test2", paramFilter = {"request"}) @GetMapping("/paramLogTest2") **public** **Map** < **String** , **Object** > **logTest2** ( **HttpServletRequest** request, **Map** < **String** , **Object** > param) { **Map** < **String** , **Object** > result = **new** **HashMap** <>(3); result.put("code", 200); result.put("msg", "success"); result.put("data", param); **return** result; } @ParamLog(value = "ParamLog-test3", paramFilter = {"request"}, callback = **LogTestCallback**.class) @GetMapping("/paramLogTest3") **public** **Map** < **String** , **Object** > **logTest3** ( **HttpServletRequest** request, **List** < **Object** > param) { **Map** < **String** , **Object** > result = **new** **HashMap** <>(3); result.put("code", 200); result.put("msg", "success"); result.put("data", param); **return** result; }
}
-
日志回调声明(实现wiki.xsx.core.log.LogCallback接口):
// 加入IOC容器,否则调用失败
@Component
@Slf4j
public class LogTestCallback implements LogCallback {
@Override
public void callback ( Annotation annotation, MethodInfo methodInfo, Map < String , Object > paramMap, Object result) {
log.info(methodInfo.getClassAllName()+”.”+methodInfo.getMethodName()+”方法的回调函数执行成功”);
}
} -
测试:
@RunWith( SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class TestParamLogControllerTest {@Autowired **private** **TestParamLogController** testParamLogController; @Test **public** **void** **test** () { **List** < **Object** > list = **new** **ArrayList** <>(2); list.add("test-list"); **Map** < **String** , **Object** > paramMap = **new** **LinkedHashMap** <>(5); paramMap.put("key1", "hello-world"); paramMap.put("key2", 11); paramMap.put("key3", **11.11** D); paramMap.put("key4", **new** **String** []{"hello", "world"}); paramMap.put("key5", **new** **Number** []{111, 112, 113}); list.add(paramMap); **this**.testParamLogController.logTest1( **null** , paramMap); **this**.testParamLogController.logTest2( **null** , paramMap); **this**.testParamLogController.logTest3( **null** , list); }
}
