Error running ‘Tomcat 9’: Address localhost:1099 is already in use

Error

reason

Port 1099 is occupied, so Tomcat cannot be started

resolvent

    Win + R enter CMD to open the DOS window, use netstat – aon|findstr 1099 command to see what occupies port 1099, and use taskkill/PID 1220/F command to end the process

    Pay attention to what proportion is found. Enter the corresponding number after the PID

[Solved] Rocketmq installation error: org.apache.rocketmq.remoting.exception.remotingconnectexception: connect to failed

1. Rocketmq org.apache.rocketmq.remoting.exception.remotingconnectexception: connect to failed
solution: modify the broker configuration in the server and add the server IP (public network)

vim /home/prod/rocketmq-all-4.3.0/distribution/target/apache-rocketmq/conf/broker.conf

add a new line
brokerIP1=xx.xx.xx.xx  # your public IP

Then restart the process, restart the broker must use the configuration file to start
nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf &

Meanwhile, if you use alicloud, you must release port 10909, dashboard port 9876 in the security rules

The reason is that after integrating swagger, an interface of the controller layer receives two entity classes with the same name. Chestnut: in a controller

@ApiOperation(value = "分页查询", notes = "分页查询")
@GetMapping("/page")
public R getPmFcPerformanceBondPage(PageDto page, PmFcPerformanceBond pmFcPerformanceBond, PmFcBidBond pmFcBidBond) {
   QueryWrapper<PmFcPerformanceBond> query = WrapperBuilder.generateQuery(pmFcPerformanceBond, page);
   return R.ok(pmFcPerformanceBondService.page((Page) page, query));
}

It is caused by the same parameters in classes pmfcperformancebond and pmfcbidbond.

[Solved] SpringBoot Startup Error: Unable to start LiveReload server

WARN 12000 — [ restartedMain] o.s.b.d.a.OptionalLiveReloadServer : Unable to start LiveReload server

Article catalog

Cause of problem: solution:

problem

0000-00-00 00:00:55.497  WARN 12000 --- [  restartedMain] o.s.b.d.a.OptionalLiveReloadServer       : Unable to start LiveReload server

reason:

When you use the springboot hot deployment plug-in devtools , and start multiple applications at the same time, the console will report this warning;

The problem is that a port is configured in devtoolsproperties. The default is 35729

       public static class Livereload {
                private boolean enabled = true;

                private int port = 35729;

        ... }

Multiple ports are in conflict, causing the hot deployment plug-in behind to not take effect.

Solution:

Add the following configuration to the application.properties file:

spring. Devtools. Livereload. Port = 35731 (specified port does not duplicate port)

Dubbo stipulates that the interface name with empty return value in the service interface cannot start with get!

Change the name of the method starting with get or add the return value type.

# Redis database index (default is 0)
spring.redis.database=0
# Redis server address
spring.redis.host=localhost
# Redis server connection port
spring.redis.port=6379
# Redis server connection password (default is empty)
spring.redis.password=
# Maximum number of connections to the connection pool (use negative values to indicate no limit)
spring.redis.pool.max-active=1000
# Maximum connection pool blocking wait time (use negative values to indicate no limit)
spring.redis.pool.max-wait=-1
# The maximum idle connections in the connection pool
spring.redis.pool.max-idle=300
# The minimum idle connections in the connection pool
spring.redis.pool.min-idle=100
# Connection timeout (milliseconds)
spring.redis.timeout=60000

Check whether the configuration bind 127.0.0.1 in redis.windows-service.conf file is the local IP address
the maximum number of connections in the redis connection pool can only alleviate the concurrency to a certain extent. In stand-alone applications, redis is a single thread. Even if the configuration is large, it can not fundamentally solve the problem. It is recommended to build a redis cluster.

Error reporting reason:
a small part of the source code of the Druid connection pool

public abstract class DruidAbstractDataSource{
 	protected volatile String username;
 	protected volatile String password;
	protected volatile String driverClass;
	protected Driver driver;
}

In xml set injection is given the wrong name
<property name="driver" value="${jdbc.driver}"/>
Solution:
Change <property name="driver" value="${jdbc.driver}"/>to
<property name="driverClassName" value="${jdbc.driver}"/>

Solution: it is not enough to rely only on spring boot starter web in the parent project. You should add

	<parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.1.0.RELEASE</version>
    </parent>

Just start again.

Gateway Error: allowedOrigins cannot contain the special value “*“ 

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain 
the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response 
header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

Error has been observed at the following site(s):
	|_ checkpoint ⇢ org.springframework.cloud.gateway.filter.WeightCalculatorWebFilter [DefaultWebFilterChain][from www.fhadmin.cn]

The reason for the problem is that the new version of gateway cancels allowedorigins and the corresponding change is   allowedOriginPatterns

The configuration is modified to:
