Java Lambda Wrapper for Exception Java的Lambda一些Wrapper。模拟kt操作

JavaLambda.java

@Slf4j
public class BizUtils {

    public static<R> R invoke(Function<Void,R> function, R  defaultValue){
        try {
            return function.apply(null);
        } catch (Exception e) {
            log.error("try method failed", e);
            return defaultValue;
        }
    }

    public static String invokeS(Function<Void,String> function, String defaultValue){
        var result=invoke(function,defaultValue);
        if(result.isEmpty()){return defaultValue;}
        return result;
    }

    public static<T,R> R ignoreError(Function<T,R> function, T args)
    {
        try {
            return function.apply(args);
        } catch (Exception e) {
            log.error("try method failed", e);
            return null;
        }
    }

}

//File file=BizUtils.invoke(item->new File("xxxx"),aaaa);
