同样的jar包使用beanshell Sampler可以测试，使用JSR223 Sampler报错
Java方法导出jar包，使用测试计划添加，或放入lib包，或ext包下
public class Aal {
public int add(int a,int b){
return a+b;
}
}
jar包内容：
jmeter beanshell Sampler脚本
java;gutter:true;
import Aal;Aal aal = new Aal();
int res=aal.add(1,5);
log.info("<strong><em>*</em></strong><strong><em>*</em></strong><strong><em>*</em></strong>**"+res);</p>
<pre><code>
**beanshell Sampler调用测试**
日志输出：
INFO o.a.j.u.BeanShellTestElement: ***********************6
**JSR223 Sampler 调用测试**
日志输出：说明引入的jar包有问题
;gutter:true;

重写打包测试成功
JSR223 Sampler 调用测试，日志输出成功
import Test.*;
Add add = new Add();
int res=add.add(1,5);
//System.out.println("*********res:"+res);
log.info("***********************"+res);
总结：
1、打完jar后，查看jar里面是class文件，还是java文件，java 用JSR223 Sampler可能引用不到；
2、用JSR223 Sampler时，注意打jar包时的类文件在一个package下面，没有package用JSR223 Sampler可能引用不到；
3、测试计划加入jar后，在JSR223 Sampler中要引入，不引入JSR223 Sampler可能找不到类；
4、有时候引入jar后，可能要重启jmeter；
JSR223 Sampler 直接写方法测试
java;gutter:true;
public class Aal {
public int add(int a,int b){
return a+b;
}</p>
<p>}
Aal aal = new Aal();
int res1=aal.add(1,5);
log.info("<strong><em>*</em></strong><strong><em>*</em></strong><strong><em>*</em></strong><strong><em>*</em></strong><strong><em>*</em></strong><strong><em>*</em></strong>**res1:"+res1);
日志输出：
INFO o.a.j.p.j.s.J.JSR223 Sampler: ********res1:6
