Error reporting reason

Websocket needs to be started by relying on containers such as Tomcat

Solution:

Add “webenvironment = springboottest. Webenvironment. Random_port” after springboottest, which means to create a web application context.

For a complete example, refer to the following code:

package org.jeecg;

import lombok.extern.slf4j.Slf4j;
import org.jeecg.modules.info.cache.DataCache;
import org.jeecg.modules.info.service.IWrSeasonBService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;


@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class DataCacheTest {

    @Autowired
    DataCache dataCahche;

    @Autowired
    IWrSeasonBService iWrSeasonBService;


    @Test
    public void irrSeasonTest() {
        log.info("========================");
        log.info("irrigation season cache test");
        log.info("irrigation season name:" + "spring irrigation");
        String str = dataCahche.getStartEndDateBySeasonNm("spring irrigation");
        // assertEquals("2021-03-01,2021-04-30", str);
        String[] arr = str.split(",");
        if (arr != null && !arr.equals("null")) {
            log.info("Start date, end date:" + arr[0] + "," + arr[1]);
        } else {
            log.info("Record cache does not exist");
        }
        log.info("========================");
    }

}

How to Solve Swagger error: typeerror: failed to fetch

Scene description

A project was recently deployed. Because it is compatible with IE8, the front and back ends need to be deployed to a site. The nginx configuration is as follows:

server {
    listen       80;
    server_name www.aaa.ink;
	client_max_body_size  1000M;
	client_body_timeout 20s;
	client_header_timeout 10s;
	send_timeout 30s;
	ssl_protocols TLSv1.2;
    charset utf-8;
	location ^~ /api/ {
		proxy_pass http://127.0.0.1:8080/api/;
	}
    
    location ~/(.*)$ {
        root   /usr/local/nginx/ttm;
        index  index.html index.htm;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

Swagger is used as the interface document in the background. After the project is started, the site can be accessed normally, but an error will be reported when testing the interface in swagger. The error prompt is typeerror: failed to fetch

Problem analysis

Analysis shows that swagger’s actual request address becomes http://127.0.0.1:8080/api/ , it’s not what we actually do http://www.aaa.ink/api/ Interface address. It is found that swagger will obtain a server address according to the user’s request. Due to the use of nginx reverse proxy, swagger obtained the intranet address we configured, resulting in the request unable to respond normally.

Problem solving

location ^~ /api/ {
	proxy_set_header Host $host;
	proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
	proxy_set_header X-Forwarded-Host $server_name;
	proxy_pass http://127.0.0.1:8080/api/;
}

Set the forwarding of background items to the request header so that swagger can get the real address. The problem can be solved.

Springboot integration RabbitMQ times error: Failed to check/redeclare auto-delete queue(s).

Today, when the company server rabbitmq related configuration is changed to local related configuration in the code, an error is reported: failed to check/redeclare auto delete queue (s)

Error reporting reason:

15672 is the port of the web management interface; 5672 is the port accessed by MQ, so changing the port in the configuration file to 5672 is OK;

Fastjson Error: Error: Cannot create inner bean ‘org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

Error: Cannot create inner bean ‘org.springframework.http.converter.json.MappingJackson2HttpMessageConverter#0

The spring-mvc.xml configuration file is written like this

 <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                 <property name="objectMapper">
                     <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
                         <property name="failOnEmptyBeans" value="false"/>
                     </bean>
                 </property>
             </bean>

reason:

Only the fastjosn dependency is imported, and the following dependency is not imported

 <dependency>
             <groupId>com.fasterxml.jackson.core</groupId>
             <artifactId>jackson-databind</artifactId>
             <version>2.12.4</version>
         </dependency>

These three jar packages are missing from the generated package

jackson-annotations-2.12.4.jar jackson-databind-2.12.4.jar jackson-core-2.12.4.jar

The problem is solved after importing dependencies.

The writing method of the new version of MySQL driver is different from that of the previous version. Jar package 8.0. * everything is common

Reference log:

code:

Interface scenario: the data transmitted by the body is relatively large. Gzip compression has been used.

Error analysis reason: the message content is large, and some of them have not been transmitted in the past. Therefore, JSON parsing reports an error.

Openfeign uses the httpurlconnection provided by JDK by default. We know that httpurlconnection has no connection pool and its performance and efficiency are relatively low. If the default is adopted, it is likely to encounter performance problems and lead to system failure.

Solution:

Change to okhttpclient mode:

feign.okhttp.enabled=true

ribbon.okhttp.enabled=true

Result: the interface is called normally. As shown below:

Add: it is said on the Internet that the combination of @ getmapping method and @ ResponseBody will report errors. I wrote a test interface filebase (such as the code posted above). The @ getmapping method used with @ ResponseBody has no impact@ The restcontroller interface has the annotation of @ ResponseBody (as shown in the figure below).

The operation results are shown in the following two figures:
