The introduction of third-party jar package in mavn project results in classnotfoundexception

Cases

I have a maven built project. There are dependencies between the project modules. I need to use a local jar package, which cannot be configured pom.xml The file is automatically downloaded from the remote warehouse, so I directly import the jar package to one of the projects without passing the pom.xml As a result, other modules that depend on the module cannot reference the jar, and classnotfoundexception appears tion

In this project, there are the following dependencies between modules:

The project needs to introduce fastdfs_ client_ V1.20.jar package is used to operate the fastdfs distributed file system. Both service and controller are involved in the operation. So now we want to put the operation tool class of fastdfs in the common module for sharing. But now the common module directly uses fastdfs_ client_ If v1.20.jar is imported through lib, because this method is not built through maven, so service In other words, even if the tool class is placed in the common module, neither the service nor the web module can access the tool class and import the corresponding package. When running the whole web project and uploading the file to the fastdfs system, classnotfoundexception will appear, unless both the service and the web module can inherit Fastdfs in common module_ client_ The jar package v1.20.jar

Solutions

1. Find the specific location of the package

2. Open the CMD and enter the directory of the third party jar package

3. Run the command to build the jar package manually

mvn install:install-file -Dfile=D:\Users\10856214\workspace-template\fastDfs\lib\fastdfs_client_v1.20.jar -DgroupId=fastdfs_client -DartifactId=fastdfs_client -Dversion=1.20 -Dpackaging=jar -DgeneratePom=true

4. Check the local warehouse to see if the jar package has been added to the local warehouse folder

5. Give the jar package to Maven for management and add it to pom.xml in

<span style="white-space:pre">		</span><dependency>
<span style="white-space:pre">			</span><groupId>fastdfs_client</groupId>
<span style="white-space:pre">			</span><artifactId>fastdfs_client</artifactId>
<span style="white-space:pre">			</span><version>1.20</version>
<span style="white-space:pre">		</span></dependency>

6. Restart Maven install common module to see if the service and web modules have been imported into the common module’s tool classes

[How to Solve] java.lang.IllegalArgumentException: Request header is too large

background

Today, when I used springboot to develop my blog system, the following exception always appeared when I click Submit markdown file in the browser:

java.lang.IllegalArgumentException: Request header is too large

The web technology stack used is springboot, with Tomcat service embedded

Solution

After troubleshooting, it is because the server has a request length configuration. You can see from the source code of the server configuration class serverproperties that there are the following parameters:

/**
     * Maximum size, in bytes, of the HTTP message header.
     */
    private int maxHttpHeaderSize = 0; // bytes

There is a HTTP header maximum value setting, the unit is byte, as long as the application.properties The maximum value of file configuration is enough

#Request header length limit
server.max-http-header-size=10000000

[How to Fix] manual close is not allowed over a Spring managed SqlSession

Background:

Today, I started an old project, and the console printed the following exception, which probably means that manual closing is not allowed on spring hosted sqlsession:

Solution

After the above description of the exception stack, it is obvious that the sqlsessiontemplate is manually closed. It is obvious that it is not manually closed here, which means that the framework helps us close the sqlsessiontemplate. Look at the source code of sqlsessiontempate


  /**
   * {@inheritDoc}
   */
  @Override
  public void close() {
    throw new UnsupportedOperationException("Manual close is not allowed over a Spring managed SqlSession");
  }

The close() method of sqlsessiontemplate throws an exception, because it does not allow the method to be called directly to close, but automatically closes every time a transaction is executed.

/**
   * Proxy needed to route MyBatis method calls to the proper SqlSession got
   * from Spring's Transaction Manager
   * It also unwraps exceptions thrown by {@code Method#invoke(Object, Object...)} to
   * pass a {@code PersistenceException} to the {@code PersistenceExceptionTranslator}.
   */
  private class SqlSessionInterceptor implements InvocationHandler {
    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
      SqlSession sqlSession = getSqlSession(
          SqlSessionTemplate.this.sqlSessionFactory,
          SqlSessionTemplate.this.executorType,
          SqlSessionTemplate.this.exceptionTranslator);
      try {
        Object result = method.invoke(sqlSession, args);
        if (!isSqlSessionTransactional(sqlSession, SqlSessionTemplate.this.sqlSessionFactory)) {
          // force commit even on non-dirty sessions because some databases require
          // a commit/rollback before calling close()
          sqlSession.commit(true);
        }
        return result;
      } catch (Throwable t) {
        Throwable unwrapped = unwrapThrowable(t);
        if (SqlSessionTemplate.this.exceptionTranslator != null && unwrapped instanceof PersistenceException) {
          // release the connection to avoid a deadlock if the translator is no loaded. See issue #22
          closeSqlSession(sqlSession, SqlSessionTemplate.this.sqlSessionFactory);
          sqlSession = null;
          Throwable translated = SqlSessionTemplate.this.exceptionTranslator.translateExceptionIfPossible((PersistenceException) unwrapped);
          if (translated != null) {
            unwrapped = translated;
          }
        }
        throw unwrapped;
      } finally {
        if (sqlSession != null) {
          closeSqlSession(sqlSession, SqlSessionTemplate.this.sqlSessionFactory);
        }
      }
    }
  }

As you can see above, every time the invoke method is called, the session will be automatically closed.

Because mybatis is integrated with spring, the instance is managed by spring. At this time, it is triggered to close, which should be related to the initialization failure of the spring container. After further investigation, an exception is found:

Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'brokerURL' threw exception; nested exception is java.lang.IllegalArgumentException: Invalid broker URI: tcp://###:61616
    at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:101)
    at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:57)
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1420)
    ... 140 more

As can be seen from the above exception, it is caused by a configuration invalid broker URI: TCP:// ################ error, which causes spring container initialization failure and triggers spring to call the destroy method of disposablebeanadapter . Later, you only need to change the configuration to start normally.

Most of the problems are caused by other exceptions. First, check whether there are other exceptions in or other beans fail to load . If you don’t want to see the exception again and want to permanently shield the exception, just add scope = "prototype" to it. The reason is that spring’s bean is singleton by default. Now it is changed to scope = "prototype" to indicate that an independent sqlsessiontemplate instance is created for each call. In this way, if a class fails to load, the call will not be affected.

<!-- SqlSession template class example -->
    <bean id="sessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"
        destroy-method="close" scope="prototype">
        <constructor-arg index="0" ref="sqlSessionFactory" />
    </bean>

Redis Exception | DENIED Redis is running in protected mode because protected mode is enabled

background

Today, I set up a redis environment to test whether it is normal with simple code,

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootRedisApplicationTests {

    @Autowired
    StringRedisTemplate stringRedisTemplate;

    @Test
    public void saveString() {
        stringRedisTemplate.opsForValue().set("accountId","123456");
        Assert.assertEquals("123456",stringRedisTemplate.opsForValue().get("accountId"));
    }

}

The results are as follows

org.springframework.data.redis.RedisSystemException: Redis exception; nested exception is io.lettuce.core.RedisException: io.lettuce.core.RedisConnectionException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

./redis-server

Later, start the command and add redis.conf configuration can connect normally

./redis-server ../redis.conf

[error] error handling of IntelliJ idea

ClassNotFoundExceptionEmpty test suitejavalangNoClassDefFoundError

ClassNotFoundException

Error report:
once IntelliJ idea is running, it will report an error, and no class can be found
in the system java.lang.ClassNotFoundException

Solution:
open project structures (ALT + Ctrl + Shift + s) to check whether the directory set by project – out and module – path – out exists.
Generally, the module – path – out is set under the target directory, but if there is no target directory at the first run, it must be generated by Maven build, so either change the out path or run Maven build first.

Empty test suite

Error:
JUnit running times cannot find the test group
process finished with exit code 1
class not found:“ XXX.XXXTest ”Empty test suite.

Solution:
Run Maven test and download relevant jar packages

java.lang.NoClassDefFoundError

Error:
minaserver logger – & gt; error{ ContextLoader.java:336 }-Context initialization failed java.lang.NoClassDefFoundError : Lcom/cebbank/gage/dao/UserDao;

Solution:
if you want to change the project name, remember to delete all the configuration files (. IML,. Idea, etc.) and leave only the folder and folder of the project code pom.xml File, and then re import the Maven project.

SyntaxError: unexpected EOF while parsing

Error in the eval() function
Correct code snippet:

with open("COCO_train.json", "r+") as f:
    data = f.readline()
    data = data.strip('{').split('{')
    del data[0]
    del data[-1]
for i in data:
    i = '{' + i[: -2]
    i = eval(i)

Error code segment:

with open("COCO_train.json", "r+") as f:
    data = f.readline()
    data = data.strip('{').split('{')
    del data[0]
for i in data:
    i = '{' + i[: -2]
    i = eval(i)

The general reason for this error is that the format is not correct. This error occurs when the blogger converts the string into a dictionary, because the last string is missing the} character, so delete it.

c:\Git\bin\ssh.exe: *** Couldn’t reserve space for cygwin’s heap, Win32 error 487

Today, suddenly uploading code to the code cloud with AS failed and there was a problem
Tried to save uncommitted changes in stash before Update, but failed with an error. stash file://D:/AndroidStudioProjects/VRvr: 0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487 AllocationBase 0x0, BaseAddress 0x68550000, RegionSize 0x1E0000, State 0x10000 C:\Program Files (x86)\Git\bin\sh.exe: *** Couldn’t reserve space for cygwin’s heap, Win32 error 0
Found click Git bash flash back
Looked up a lot of data on the net also made along while, my solution is as follows
1. Reinstalled git client first
Find it useless
2. Run the CMD window
perform

c:\msysgit\bin>rebase.exe -b 0x50000000 msys-1.0.dll

Found in

ReBaseImage (Msys-1.0.DLL) failed with last error = 6
A few more runs still won’t do
3. According to the Internet
It is still useless to copy out the Msys-1.0.DLL under C:\Program Files (x86)\Git\bin and then copy it in.
Solutions;
Finally, I executed step 2 as an administrator and it was successful
Run as an administrator:
Find the CMD. Exe file under C:\Windows\System32, right-click and select Run as administrator — ‘OK

IsADirectoryError: [Errno 21] Is a directory: ‘/home/user8/Desktop/low_light/Learning-Texture-Invari

The reason is that only the file path is specified, not the filename and suffix.
