如何找到两个数组中字符串之间的匹配-java[duplicate]

Question

abcd                    
efgh            
servicegroup_1
ijkl 

servicegroup_3
servicegroup_1

我实现了以下代码：

for (int i = 0; i < scopeFile.length; i++) {
                for (String element : scopeJWT) {
                    if (scopeFile[i].contains(element)) {
                        ctx.setSendZuulResponse(true);
                        System.out.println(now + " --- " + "[Check Signature: OK]" + " [Verify Scope: OK]" + " [Verify expTime: OK]");
                    } else {
                        ctx.setSendZuulResponse(false);
                        ctx.setResponseStatusCode(HttpStatus.UNAUTHORIZED.value());
                        System.err.println(now + " --- " + "[VERIFY SCOPE: KO]");
                    }
                }
}

但是，它同时返回verify scope:OK和verify scope:KO，即使在考虑我报告的数组时，我只打印verify scope:OK（因为数组#1包含ServiceGroup_1)

有什么办法可以修正我的代码吗？谢谢你

您忘记在Array1中找到字符串后中断循环。尝试在此行后添加分符；:

System.out.println(now + " --- " + "[Check Signature: OK]" + " [Verify Scope: OK]" + " [Verify expTime: OK]");

并检查循环外的非OK大小写。

像这样：

boolean isOk = false;
for (int i = 0; i < scopeFile.length; i++) {
    for (String element : scopeJWT) {
        if (scopeFile[i].contains(element)) {
            ctx.setSendZuulResponse(true);
            System.out.println(now + " --- " + "[Check Signature: OK]" + " [Verify Scope: OK]" + " [Verify expTime: OK]");
            isOk = true;
            break;
        }
    }
}
if (!isOk) {
    ctx.setSendZuulResponse(false);
    ctx.setResponseStatusCode(HttpStatus.UNAUTHORIZED.value());
    System.err.println(now + " --- " + "[VERIFY SCOPE: KO]");
}
