### 介绍
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
1. 添加依赖：

```
<dependency>
    <groupId>wiki.xsx</groupId>
    <artifactId>slf4j-spring-boot-starter</artifactId>
    <version>1.2.0</version>
</dependency>
```
2. 开启日志：

yml方式：

```yaml
logging:
  level:
    wiki.xsx.core: 对应级别
```
properties方式：

```properties
logging.level.wiki.xsx.core=对应级别
```

#### 二、开始使用（使用DEBUG模式）
##### @ParamLog注解示例：

1. 日志注解标记：
```java
@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;
    }
}
```
2. 日志回调声明（实现wiki.xsx.core.log.LogCallback接口）：
```java
// 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");
    }
}
```
3. 测试：
```java
@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", 11.11D);
        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);
    }
}
```
4. 日志打印效果：

    @ResultLog(value = "ResultLog-test1")
    @GetMapping("/resultLogTest1")
    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;
    }

    @ResultLog(value = "ResultLog-test2", callback = LogTestCallback.class)
    @GetMapping("/resultLogTest2")
    public Map<String, Object> logTest2(HttpServletRequest request, List<Object> param) {
        Map<String, Object> result = new HashMap<>(3);
        result.put("code", 200);
        result.put("msg", "success");

### 其他说明

#### 日志类型
1. @ParamLog：参数类型，仅打印参数
2. @ResultLog：结果类型，仅打印结果
3. @ThrowingLog：异常类型，仅打印异常
4. @Log：综合类型，打印参数+结果+异常

#### 日志参数
1. value：业务名称
2. level：日志级别，默认DEBUG
3. position：代码定位，默认DEFAULT
4. paramFilter：参数名过滤，默认{}
5. callback：日志回调，默认VoidLogCallback.class（实现wiki.xsx.core.log.LogCallback接口，且需放入IOC容器中）

#### 日志级别
1. DEBUG(默认): 调试级别
2. INFO: 信息级别
3. WARN: 警告级别
4. ERROR: 错误级别

#### 回调接口说明
```java
public interface LogCallback {

    /**
     * 回调方法
     * @param annotation 当前使用注解
     * @param methodInfo 方法信息
     * @param paramMap 参数字典
     * @param result 方法调用结果
     */
    void callback(
            Annotation annotation,
            MethodInfo methodInfo,
            Map<String, Object> paramMap,
            Object result
    );
}
```

#### 特别说明
1. 日志级别为DEBUG时，默认开启代码定位，方便调试
2. 其他级别默认关闭代码定位，减少不必要的开支，如需要可手动开启(position=Position.ENABLED)
