Check if class exists in Java classpath without running its static initializer?
提问by Epaga
If I use
如果我使用
try {
Class.forName("my.package.Foo");
// it exists on the classpath
} catch(ClassNotFoundException e) {
// it does not exist on the classpath
}
the static initializer block of "Foo" is kicked off. Is there a way to determine whether a class "my.package.Foo" is on the classpath without kicking off its static initializer?
“Foo”的静态初始化块被启动。有没有办法在不启动静态初始化程序的情况下确定类“my.package.Foo”是否在类路径上？

Try the forName(String name, boolean initialize, ClassLoader loader)method of Classand set the param initializeto false.
尝试forName(String name, boolean initialize, ClassLoader loader)方法Class并将参数设置initialize为false。
