无法使用 Eclipse 在 Java 中解决 PMD 错误

Question

I have created a below java service in eclipse and reviewed the code using PMD plugin I'm getting below errors

** Errors **

DataflowAnomalyAnalysis: Found 'DD'-anomaly for variable 'result' (lines '80'-'83').
SignatureDeclareThrowsException: A method/constructor should not explicitly throw java.lang.Exception

java service

@GetMapping("OCR/GetBarcodeRead")
    @ApiOperation("Get result from Barcode Zxing library")
    public String getBarcodeRead() throws Exception {

        String result = new String();

        try {
            result = service.zxing();
        } catch (Exception e) {
            System.out.println(e);
            result = "";

        }

        return result;

    }

Could someone help me to resolve this issue? Thanks in advance

Answer 1

Your method declaring you throwing Exception , but you aren't, so remove it

public String getBarcodeRead() {

Also remove new String() and initialize it with ""

String result = "";
