【编程语言】Jfinal AOP 用法整理

用法

需要实现 implements Interceptor

代码示例

import cn.hutool.core.util.StrUtil;
import cn.hutool.json.JSONUtil;
import cn.hutool.log.Log;
import cn.hutool.log.LogFactory;
import com.jfinal.aop.Interceptor;
import com.jfinal.aop.Invocation;

import java.util.Arrays;


public class MessageAop implements Interceptor {

    private static final Log LOG = LogFactory.get();

    @Override
    public void intercept(Invocation inv) {

        LOG.info("之前");
        inv.invoke();
        LOG.info("之后");
        //参数
        Object[] args = inv.getArgs();
        Arrays.stream(args).forEach(o->LOG.info(StrUtil.format("{}", o)));

        //返回值
        Object returnValue = inv.getReturnValue();
        System.out.println(JSONUtil.parseObj(returnValue).toStringPretty());

    }
}
