【问题描述】：

我正在使用 JSR223 Sampler 并尝试进行算术运算..

try {
    setStrictJava(true);
    int a=1;
    int b=2;
    int c = a+b;
    vars.put("c",c);
} catch(Exception ex) {
    log.error("something wrong", ex);
    throw ex;
}

出现以下错误..

如何解决？

【解决方案1】：

您需要convert your variable to String 才能使用vars.put() 功能，例如：

vars.put("c", String.valueOf(c));

或者改用vars.putObject()函数

vars.putObject("c", c);

另外请注意，您应该使用Groovy language in the JSR223 Sampler，在这种情况下，您必须删除setStrictJava(true); 行，否则您的代码将无法工作。

【解决方案2】：

您必须将数字变量转换为字符串：

int a = 1;
int b = 2;
int c = a + b;
vars.put("c", c.toString());
