springboot 启动项目打印接口列表
环境
- springboot 2.3.2.RELEASE
修改配置文件
logging: level: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping: trace
结果：
Springboot项目添加接口入参统一打印
需求：要求接口被调用时要打印被调用方法名，以及入参情况，参数格式化时选择fastjson
注：使用fastjson序列化时脱敏，建议入参统一使用自定义的对象类型作为入参
如果不需要参数脱敏，直接使用增强中相关代码，并去除参数脱敏相关代码即可
新建注解，用于实现参数打印功能的增强
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface ParamInfo {
/**
* 取消统一打印参数
* 默认为false统一打印
* 如需自定义参数打印 请赋值为true
*/
boolean unPrint() default false;
/**
* 需要脱敏的字段，如密码等
*/
String[] fields() default {};
}
自定义序列化规则
/**
* 序列化过滤器：值替换
*
*/
public class ReplaceFieldFilter implements ValueFilter {
/**
* 需要进行替换的属性名和替换值
* key：属性名
* value：替换值
*/
private Map<String, Object> fieldMap;
public ReplaceFieldFilter() {
}
public ReplaceFieldFilter(Map<String, Object> fieldMap) {
this.fieldMap = fieldMap;
}
@Override
public Object process(Object o, String name, Object value) {
if(!CollectionUtils.isEmpty(fieldMap)){
Iterator<Map.Entry<String, Object>> iterator = fieldMap.entrySet().iterator();
while (iterator.hasNext()){
Map.Entry<String, Object> next = iterator.next();
if(next.getKey().equalsIgnoreCase(name)){
return next.getValue();
}
}
}
return value;
}
public Map<String, Object> getFieldMap() {
return fieldMap;
}
public void setFieldMap(Map<String, Object> fieldMap) {
this.fieldMap = fieldMap;
}
/**
* 传入需要脱敏的字段名，序列化时格式化为 * 号
*/
public ReplaceFieldFilter(String... fields) {
String str = "******";
fieldMap = new HashMap<>(4);
for (String field : fields) {
fieldMap.put(field, str);
}
}
}
写参数打印增强，这里选择环绕增强
@Component
@Aspect
//表示增强的执行顺序，如果多个增强，数值小的先被执行
@Order(0)
public class ParamInfoAspect {
private static final Logger LOGGER = LoggerFactory.getLogger(ParamInfoAspect.class);
@Around("execution(* com.service.impl.*.*(..))")
public Object printParam(ProceedingJoinPoint joinPoint) throws Throwable {
long startTime = System.currentTimeMillis();
String requestId = RandomStringUtils.randomAlphanumeric(16);
Object returnValue = null;
try {
Object[] args = joinPoint.getArgs();
// 获取方法对象
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
//通过注解获取脱敏字段，之后初始化fieldMap，完成字段脱敏
ParamInfo annotation = method.getAnnotation(ParamInfo.class);
Map<String, Object> fieldMap = new HashMap<>(4);
fieldMap.put("password", "******");
if (annotation != null) {
//获取需要脱敏的字段名数组
String[] fields = annotation.fields();
for (String field : fields) {
fieldMap.put(field, "******");
}
}
String param;
//参数整合，多字段入参整合为对象，单个对象入参格式不变
if (args.length > 1 || (args.length == 1 && args[0].getClass() == String.class)) {
Map<String, Object> paramMap = new LinkedHashMap<>();
String[] parameterNames = signature.getParameterNames();
for (int i = 0; i < parameterNames.length; i++) {
paramMap.put(parameterNames[i], args[i]);
}
param = "[" + JSON.toJSONString(paramMap, new ReplaceFieldFilter(fieldMap)) + "]";
} else {
param = JSON.toJSONString(args, new ReplaceFieldFilter(fieldMap));
}
String methodName = method.getName();
LOGGER.info("method:[{}], parameter:{}, requestId:[{}]", methodName, param, requestId);
returnValue = joinPoint.proceed();
return returnValue;
} catch (Exception e) {
LOGGER.error("system is error:", e);
//可在这里定义程序异常时的错误返回值
returnValue = ErrorCode.SYSTEM_ERROR;
return returnValue;
} finally {
LOGGER.info("request cost:{}ms, requestId:[{}]", System.currentTimeMillis() - startTime, requestId);
LOGGER.info("returnValue:[{}], requestId:[{}]", returnValue, requestId);
}
}
}
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
