java - Java中的静态方法

查看一些Java代码，这似乎不正确。在我看来，每次调用项目时，您都会获得一个新的哈希图，因此该语句始终为false

projects.get(soapFileName) != null

似乎它应该有一个支持领域

public static HashMap<String,WsdlProject> projects = new HashMap<String,WsdlProject>();

public Object[] argumentsFromCallSoapui(CallT call, Vector<String> soapuiFiles, HashMap theDPLs,int messageSize)
{
    try {
        for (String soapFileName:soapuiFiles){
            System.out.println("Trying "+soapFileName);
            WsdlProject project ;
            if (projects.get(soapFileName) != null){
                project = projects.get(soapFileName);
            } else {
                project = new WsdlProject(soapFileName);
                projects.put(soapFileName,project);
            }
        }
    } ...
}

最佳答案

不。在Java中，静态变量仅初始化一次。

因此，这条线只会被调用一次。

public static HashMap<String,WsdlProject> projects = new HashMap<String,WsdlProject> ();
