Spring boot AOP无法与maven一起工作

Question

我正试图在自定义注释和Around建议的帮助下在spring-boot中实现AOP。我在GET api之前添加了注释，但我无法在我的方面中捕获函数。

pom.xml

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>

HiveService.java

@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.METHOD })
public @interface HiveService{
//public String name() default "";
}

Followup.java

@HiveService
@RequestMapping(value="rest/services/{pr 
oduct}", method = RequestMethod.GET, produces = "application/json; charset=UTF-8")
public String getFollowupCategoryList(@PathVariable String product) {
LOGGER.info("[getFollowupCategoryList]: started again ");
}

HiveConsumer.java

@Aspect
@Component
public class HiveConsumer {

@Around("@annotation(com.abc.xyz.HiveService)")
public Object logExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable {
long start = System.currentTimeMillis();
Logger LOGGER = LoggerFactory.getLogger(com.abc.xyz.FollowupController.class);
LOGGER.info("Before");
Object proceed = joinPoint.proceed();
long executionTime = System.currentTimeMillis() - start;
LOGGER.info(joinPoint.getSignature() + " executed in " + executionTime + "ms");
return proceed;
}
}

Spring AOP 的配置文件

@SpringBootApplication
@RestController
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class ActivitiRestApplication extends 
SpringBootServletInitializer  {

public static void main(String[] args) throws Exception {
SpringApplication.run(applicationClass, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder app) {
return app.sources(applicationClass);
}
private static Class<ActivitiRestApplication> applicationClass = ActivitiRestApplication.class;

如果

• 将依赖org.springframework.boot:spring-boot-starter-web:2.0.3.RELEASE添加到POM中
• 删除冗余的CCD_ 2，因为它是CCD_
• 将@RestController添加到包含带注释方法的类中
• make方法getFollowupCategoryList(..)实际上返回了一个字符串(在示例代码中，它不返回任何内容，因此甚至不编译(

这是作为完整MCVE的代码的固定版本，即包括包和类名。为了这个演示，我将日志记录代码更改为使用System.out，以便最大限度地减少依赖性。

更新：实际上，您甚至可以将POM减少为：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>de.scrum-master.stackoverflow</groupId>
<artifactId>spring-boot-51512380</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
<version>2.0.3.RELEASE</version>

<dependency>

<artifactId>spring-boot-starter-web</artifactId>
<version>2.0.3.RELEASE</version>
<scope>compile</scope>
</dependency>
</dependencies>
</project>

package de.scrum_master.app;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.METHOD })
public @interface HiveService {
//public String name() default "";
}

package de.scrum_master.app;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class SomeClass {
@HiveService
@RequestMapping(value = "rest/services/{product}", method = RequestMethod.GET, produces = "application/json; charset=UTF-8")
public String getFollowupCategoryList(@PathVariable String product) {
System.out.println("[getFollowupCategoryList]: started again");
return "foo";
}
}

package de.scrum_master.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class ActivitiRestApplication extends SpringBootServletInitializer {
private static Class<ActivitiRestApplication> applicationClass = ActivitiRestApplication.class;
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder app) {
return app.sources(applicationClass);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(applicationClass, args);
}
}

package de.scrum_master.app;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;
@Aspect
@Component
public class HiveConsumer {
@Around("@annotation(de.scrum_master.app.HiveService)")
public Object logExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable {
long start = System.currentTimeMillis();
System.out.println("Before");
Object proceed = joinPoint.proceed();
long executionTime = System.currentTimeMillis() - start;
System.out.println(joinPoint.getSignature() + " executed in " + executionTime + "ms");
return proceed;
}
}

现在，如果您运行应用程序并打开URLhttp://localhost:8080/rest/services/something在web浏览器中，它将在浏览器中显示foo，并在控制台上显示：

Before
[getFollowupCategoryList]: started again
String de.scrum_master.app.SomeClass.getFollowupCategoryList(String) executed in 2ms
