springboot注解Aspect

目标

本文提供一种自定义注解，来实现业务审批操作的DEMO，不包含审批流程的配置功能。
具体方案是
自定义一个Aspect注解，拦截sevice方法，将拦截的信息持久化，待审批；审批时获取持久化数据，执行目标方法。

补充说明

获取参数的泛型信息参见 Spring获取参数的泛型信息
动态调用服务参见OpenFeign根据服务名动态调用服务

一些实体类

CheckedParam

用于包装页面传进来的参数

package com.proc.model;

import java.util.List;

public class CheckedParam {

	//业务标记，由页面传入，用于审批时页面根据tagPageJs解析data，渲染到页面，审批管理员可看到审批的内容
	private String tagPageJs;
	//页面传入的原始数据
	private List<String> data;

	public String getTagPageJs() {
		return tagPageJs;
	}

	public void setTagPageJs(String tagPageJs) {
		this.tagPageJs = tagPageJs;
	}

		return data;
	}

	public void setData(List<String> data) {

}

一些Bean

PostProcess

public interface PostProcess<T> {

	//返回说明内容，审批时在页面显示
	String description(String tag, Class<?>[] parameterTypes, Object[] args);
	
	//返回代替的返回值
	T retObject(String tag, Class<?>[] parameterTypes, Object[] args);
}

TestCheckPostProcess

import org.springframework.stereotype.Component;

@Component
public class TestCheckPostProcess implements PostProcess<String> {

	@Override
	public String description(String tag, Class<?>[] parameterTypes, Object[] args) {
		return tag + "测试testCheck";
	}

	@Override
	public String retObject(String tag, Class<?>[] parameterTypes, Object[] args) {
		return tag + "返回拦截响应";
	}

}

Aspect注解

package com.proc.config;

import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.RetentionPolicy.RUNTIME;

import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import com.proc.bean.PostProcess;

@Retention(RUNTIME)
@Target(METHOD)
public @interface Checked {
	
	String tag() default ""; 

	/**
	 * @see com.proc.util.JacksonCanonicalUtil
	 * @return
	 */
	String[] paramCanonical();
	
	Class<? extends PostProcess<?>> postProcess();
}

切面类 CheckedAop

package com.proc.config;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

import com.proc.util.Base64Util;
import com.proc.util.CheckedTransmitableUtil;
import com.proc.util.PrivateTransmitableUtil;
import com.proc.util.SpringBootBeanUtil;

@Component
@Aspect
public class CheckedAop {
	
	@Autowired
	private ProcessDbService processDbService;

	//拦截Checked注释的方法
	@Pointcut("@annotation(com.proc.config.Checked)")
	public void check() {
	}
	
	@Around(value = "com.proc.config.CheckedAop.check() && @annotation(checked)")

			Object returnVal = joinPoint.proceed();
			return returnVal;
		} else {

				//不是页面调用的业务，使用注解的tag，data保存为service的参数，这时需要页面专门解析渲染
				String[] argStrs = Base64Util.toStrings(args);
				dbModel.setParamArgs(Base64Util.encodeZip(argStrs));
				dbModel.setData(Base64Util.encode(argStrs));
			} else {

			}
			dbModel.setTag(tag);

			//持久化数据
			processDbService.save(dbModel);
			return bean.retObject(tag, parameterTypes, args);
		}
	}
}

线程池配置

测试用

import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import com.alibaba.ttl.threadpool.TtlExecutors;

@Configuration
public class TaskExecutePoolConfig {

	@Bean
	public Executor processExecutor() {
		ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
		//核心线程池大小
		executor.setCorePoolSize(10);
		//最大线程数
		executor.setMaxPoolSize(10);
		//队列容量
		executor.setQueueCapacity(500);
		//活跃时间
		executor.setKeepAliveSeconds(60);
        //线程名字前缀
		executor.setThreadNamePrefix("ProcessExecutor-");
 
		executor.setRejectedExecutionHandler(new ThreadPoolExecutor.AbortPolicy());
		// 等待所有任务结束后再关闭线程池
		executor.setWaitForTasksToCompleteOnShutdown(true);
		executor.initialize();
		//用transmittable-thread-local包装，才可以正确给线程池中的线程传递数据
		return TtlExecutors.getTtlExecutor(executor);
	}
}

持久化service

为测试方便，未真正实现持久化

package com.proc.service;

import com.proc.model.ProcessDbModel;

public interface ProcessDbService {

	void save (ProcessDbModel model);
	
	ProcessDbModel get ();
}

package com.proc.service.impl;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import com.proc.model.ProcessDbModel;
import com.proc.service.ProcessDbService;

@Component
public class ProcessDbServiceImpl implements ProcessDbService {
	private static final Logger log = LoggerFactory.getLogger(ProcessDbService.class);
	
	private volatile ProcessDbModel model;

	@Override
	public void save(ProcessDbModel model) {
		this.model = model;
		log.info(model.toString());
	}

	@Override
	public ProcessDbModel get() {
		return this.model;
	}

}

审批用的service

		MAPPER.configure(MapperFeature.USE_ANNOTATIONS, false);//禁用注解功能
		MAPPER.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, DefaultTyping.EVERYTHING, JsonTypeInfo.As.PROPERTY);
	}

	@Override
	public void process(ProcessDbModel model) {

				} else {
					args.add(MAPPER.readValue(paramArgs[i], javaType));
				}
			}
		} catch (JsonProcessingException e) {
			throw new RuntimeException("反序列化对象出错", e);
		}
		
		Object ret = ProcessBeanUtil.excuteBeanMethod(
				model.getTargetClassName(),
				model.getMethodName(),
				parameterTypes.toArray(new Class<?>[0]),
				args.toArray(new Object[0])
				);
		log.info(Objects.toString(ret));
	}

开启异步功能

package com.proc;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@SpringBootApplication
@EnableAsync
public class ProcessTestApplication {

	public static void main(String[] args) {
		SpringApplication.run(ProcessTestApplication.class, args);
	}

}

测试

1. http://localhost:8080/index
2. http://localhost:8080/index2
3. http://localhost:8080/index3
   浏览器访问上面其中一个路径一次，再访问http://localhost:8080/process一次即可
