The error message is as follows.
Severe :Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis. RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions. JedisConnectionException: Could not get a resource from the pool] with root cause
Because the ip address on the linux system in the virtual machine has changed, the configuration file in springboot has forgotten to change it.
Enter [root@localhost bin]# ip addr to see the ip address
Just change the configuration file

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>java.lang.IllegalArgumentException : URI is not absolute error
Problem phenomena:
After the framework uses SSO (Spring Security OAuth2.0), the Token has been produced. When using the Token to call the interface in Postman, the console appears URI is not absolute error
Analysis of the problem:
Use breakpoints to discover that the URI received in createRequest is empty when the request is created. The first reaction is that there is a problem with the configuration. After checking the YML file, no problem is found

@Bean
protected JwtAccessTokenConverter jwtTokenConverter() {
JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
converter.setSigningKey("test");

}After the new step is commented out, add a symmetric key to the corresponding resource service, and use the PostMan call to succeed magically.

An error was reported when springboot connected to redis Servlet.service () for servlet [dispatcherServlet] in context with path [] threw e
Made a day, finally 11 o ‘clock more than solved, record once. SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException: Cannot SerializationException:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis.serializer.SerializationException: Cannot serialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.io.NotSerializableException: com.wanghaixin.springboot.model.Student] with root cause
Solution:
NotSerializable is not serialized objects, object Article cannot be serialized therefore appeared this problem.
JavaBeans to cache must implement the Serializable interface, because Spring serializes objects before storing them in Redis
For this exception, just modify the corresponding JavaBean object, mine is Student
public class Student implements Serializable

The solution
Delete/E under the maven repositories:/myRepository/repositotyExe/repositoty/com/alibaba/fastjson 1.2.32/fastjson – 1.2.32. Jar, recompile the can!
The spring boot project was first created, pom.xml The error is Maven configuration problem. How to solve it?
An error screenshot
The solution is
Will & lt; parent> Version of the change to 1.0 version, will not report wrong.
thinking
According to Baidu, many users say that the version of Maven package is too low, and the version of spring tool suit is too high.
However, my Spring Tool Suit version 4.0, the Maven package version 3.6, and the JDK version 1.8 should match each other, but it still doesn’t work.
Inadvertently, such as screenshot modification, did not report an error, the reason is unknown, who can tell me, solve.

The answer
- what went wrong: Maven plug-in version is not compatible with the Eclipse solution: to pom configuration file. The XML add & lt; maven-jar-plugin.version> 3.1.1 & lt; /maven-jar-plugin.version> With respect to OK & lt; properties> & lt; java.version> 1.8 & lt; /java.version> & lt; spring-cloud.version> Greenwich.SR1< /spring-cloud.version> & lt; maven-jar-plugin.version> 3.1.1 & lt; /maven-jar-plugin.version> < /properties>
