Background

I call WebService in Java and report an error when I call new xxxxxxxservice().

Cause analysis

When WebService creates new xxxxxxxservice(), it needs to load the URL in xxxxxxxservice first. If the URL is not loaded or the URL is null, the above error may be reported.

There are two solutions

Method 1: Add the url of the webservice’s access address to the static method, as follows:

static {
        URL url = null;
        WebServiceException e = null;
        try {
            url = new URL("http://127.0.0.1:8088/ynhrs/services/info?wsdl");
        } catch (MalformedURLException ex) {
            e = new WebServiceException(ex);
        }
        BIZSERVICE_WSDL_LOCATION = url;
        BIZSERVICE_EXCEPTION = e;
    }

You can also configure the address of WebService file, etc

Method 2: directly add the URL to new xxxxxxxservice(), as follows:

Ynhrsspspservice pspService = new Ynhrsspspservice(new URL("http://127.0.0.1:8088/ynhrs/services/info?wsdl"));

http://127.0.0.1:8088/ynhrs/services/info?wsdl is the URL of webservice

[Solved] Java Run Error: For input string: “XXX”

Background

Today, a small partner of front-end joint commissioning said that an interface reported an error.

I first glanced at the code and found no problem.

First post the code of the place where the error is reported

...
IntegralRecord integralRecord = new IntegralRecord();
integralRecord.setUid(uid);
integralRecord.setLinkType(IntegralRecordConstants.TYPE_SIGN);
integralRecord.setTitle(IntegralRecordConstants.INTEGRAL_TASK);
integralRecord.setIntegral(Integer.parseInt(amount));
integralRecord.setStatus(1);
integralRecord.setType(IntegralRecordConstants.TYPE_ADD); 
integralRecord.setMark(StrUtil.format("Free {} points for completing tasks", amount));
userIntegralRecordService.save(integralRecord);
...

Problem location
There is no choice but to debugger a line to run.

After running to

integralRecord.setIntegral(Integer.parseInt(amount));

This line, then reported an error message For input string.

This line of code, when I look at it, just does a conversion operation on the type.

Is there something wrong with the passed data?

I ran it again and found that amount=2.00

Explanation: Because the amount is shared by several places, considering that there may be a decimal situation, a String is used in the front-end pass, and the back-end uses the corresponding type for conversion according to the actual situation.

When converting, it is indeed this line that has a problem.

The specific test situation is shown below:

Then we changed it to

amount=”2″

The results are as follows

Then the problem can be defined because integer cannot recognize the case with decimals during conversion.

Problem follow up

Integer.parseInt source code

We found that parseInt finally called the following code.

public static int parseInt(String s, int radix) throws NumberFormatException{

        if (s == null) {
            throw new NumberFormatException("null");
        }

        if (radix < Character.MIN_RADIX) {
            throw new NumberFormatException("radix " + radix +
                                            " less than Character.MIN_RADIX");
        }

        if (radix > Character.MAX_RADIX) {
            throw new NumberFormatException("radix " + radix +
                                            " greater than Character.MAX_RADIX");
        }

        boolean negative = false;
        int i = 0, len = s.length();
        int limit = -Integer.MAX_VALUE;

        if (len > 0) {
            char firstChar = s.charAt(0);
            if (firstChar < '0') { // Possible leading "+" or "-"
                if (firstChar == '-') {
                    negative = true;
                    limit = Integer.MIN_VALUE;
                } else if (firstChar != '+') {
                    throw NumberFormatException.forInputString(s);
                }

                if (len == 1) { // Cannot have lone "+" or "-"
                    throw NumberFormatException.forInputString(s);
                }
                i++;
            }
            int multmin = limit/radix;
            int result = 0;
            while (i < len) {
                int digit = Character.digit(s.charAt(i++), radix);
                if (digit < 0 || result < multmin) {
                    throw NumberFormatException.forInputString(s);
                }
                result *= radix;
                if (result < limit + digit) {
                    throw NumberFormatException.forInputString(s);
                }
                result -= digit;
            }
            return negative ?result : -result;
        } else {
            throw NumberFormatException.forInputString(s);
        }
    }

Source code positioning

In the code, we can see that an error will be reported if the range is no longer specified

int digit = Character.digit(s.charAt(i++), radix);
  if (digit < 0 || result < multmin) {
    throw NumberFormatException.forInputString(s);
}

java.lang.Character.digit(char ch, int radix) method :

Returns the value of the character ch in the specified base, if the base is not in the range MIN_RADIX ≤ base ≤ MAX_RADIX or if the value of the channel is not a valid number in the specified base -1, then it is returned.

The value of radix is 10, this is because the conversion Int type is when the single character 0~9.

So if the value is not a number between 0~9 an error will be reported.

The exception thrown is forInputString.

Solution:
String interception
In this example, it is clear that only the integer part is needed, so you can specify the character “.” based on the to intercept.

Then you can convert it and it’s done.

Borrowing from a third party
Here we recommend using the NumberUtil from the hutool toolkit

You can convert similar numbers directly.

Method: NumberUtil.parseInt

 String val ="2.00";
 int i = NumberUtil.parseInt(val);

Type conversion

Because it can be determined that the value must be of numerical type.

So it can be directly converted to BigDecimal type.

BigDecimal has an intValue method, which can be called after direct conversion

 String val ="2.00";
 int i = new BigDecimal(val).intValue();

[Solved] itextpdf Read PDF File Error: Rebuild failed: trailer not found.

Recently, I used itextpdf to print invoices, but there was an error when reading the file stream. The following is the key code

ClassPathResource classPathResource = new ClassPathResource("/template/RU_HK_INVOICE_TEMPLATE.pdf");
InputStream inputStream = classPathResource.getInputStream();
reader = new PdfReader(inputStream);// read the template of pdf

The following errors are reported in the new PdfReader(inputStream) each time:

com.itextpdf.text.exceptions.InvalidPdfException: Rebuild failed: trailer not found.; Original message: xref subsection not found at file pointer

Maven will use pom XML configuration files uniformly encode the project, but some files do not need to be re encoded, such as PDF template files; After recoding, the PDF template structure may be damaged, resulting in the unavailability of the files generated after compilation, as shown in the following figure

Therefore, it is necessary to filter out the files that do not need to be encoded: filter all files with the suffix .pdf or .p8 and do not encode them uniformly. Need to be configured in the pom.xml file nonFilteredFileExtension tag

The code change adds the following servlet dependency, and it starts successfully if you remove it, but it reports an error if you remove the reference to the project.
The reason is that adding the servlet dependency caused a conflict with another dependency when packaging.

Solution

You only need to add the scope tag in the dependency to exclude the servlet-api we introduced when packaging the project, as shown below

Classification of scope

Maven’s default dependency configuration items, the default value of scope is compile, the project is often silly to distinguish between the direct default. Today to sort out maven’s scope.

compile: the default is compile, nothing is configured, which means compile. compile means that the dependent project needs to participate in the compilation of the current project, of course, the subsequent test, runtime also participate in it, is a relatively strong dependency. This is a strong dependency. It is usually included when packaging.
test: The scope is test, which means that the dependent project is only involved in the test-related work, including the compilation and execution of the test code. Typical examples are junit.
runntime: The dependent project does not need to be involved in the compilation of the project, but it is required to be involved in the later testing and runtime cycles. Compared with compile, it just skips the compilation. To be honest, in the terminal project (non-open source, internal system), the difference with compile is not very big. The API jar corresponding to the implementation of JSR×××× is compiled, and the specific implementation is runtime, which is enough for compile to know the interface. oracle jdbc driver package is a good example, and the general scope is runntime. I can use A to achieve it, or B to achieve it.
provided: provided means that it can be packaged without being packaged in, and other facilities (Web Container) will provide it. In fact, the dependency can theoretically participate in the compile, test, run, etc. cycle. It is equivalent to compile, but with the exclude action done during the packaging phase.
system: In terms of involvement, it is the same as provided, but the dependencies are not grabbed from the maven repository, but from the local filesystem.

Cause analysis:

The data structure of the geographic coordinate attribute location in ES is (latitude, longitude), and I inserted a comma in the middle when I spliced strings, resulting in an error in inserting data. Here are the really useful parts of the above code.

Real error reason:

{"error":{"root_cause":[{"type":"parse_exception","reason":"unsupported symbol [.] in 
geohash [30.871729121.81959]"}],"type":"mapper_parsing_exception","reason":"failed to parse 
field [location] of type [geo_point]","caused_by":{"type":"parse_exception","reason":"unsupported symbol [.] in geohash 
[30.871729121.81959]","caused_by":
{"type":"illegal_argument_exception","reason":"unsupported symbol [.] in geohash 
[30.871729121.81959]"}}},"status":400}

Incorrect writing:

this.location = hotel.getLatitude()+hotel.getLongitude();

Correct writing:

this.location = hotel.getLatitude()+","+hotel.getLongitude();

Solution:

Check the string before splicing, and the order (latitude and longitude) cannot be reversed, otherwise it may lead to geographical location errors.

[Solved] ApplicationContextException: Failed to start bean ‘documentationPluginsBootstrapper‘；

After testing for a long time, it is found that the reason for swagger2:

Version 3.0.0 was originally used:

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0</version>
</dependency>

It is said that:

Reason: This is because Springfox uses path matching based on AntPathMatcher, while Spring Boot 2.6.X uses PathPatternMatcher.
Solution: Configure in application.properties: spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER

After testing, no error was reported, but the search access http://localhost:8080/swagger-ui.html has 404

If it does not work like me, just add the following code in application.properties:

spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER

[Solved] RedisTemplate increment Error: io.lettuce.core.RedisCommandExecutionException: ERR value is not an intege

Redistemplate uses increment to report an error: io.lettuce.core.RedisCommandExecutionException: ERR value is not an intege

Problem analysis

We can learn from spring’s documents that spring has two rare serialization strategies for redis. One is the JDKSerializationRedisSerialzer serialization of RedisTemplate application. The serialized value contains object information, version number, class information, etc. after this serialization, a string cannot be self incremented.

The other is the StringRedisSerializer adopted by the StringRedisTemplate. This strategy converts the string value into a byte array, so the values saved in redis can be operated.
