Q: Response return Unexpected end of file from server

1. Network connection was lost
2. The server decided to close the connection
3. Something in between the client and the server (nginx, router, etc) terminated the request
4. The server-side api requires a proxy but IDEA is not configured, especially for some intranet projects

How to set IDEA proxy: Setting-> Appearance & Behavior->System Settings->HTTP Proxy

Q: Spring Get request with array/collection parameter reports 400 error

For example Url = http://localhost:8081/test?a[0].b[0].token=xxx&a[0].b[0].name=yyy

Add the following configuration:

import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class WebConfig {

    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((TomcatConnectorCustomizer) connector -> connector.setProperty("relaxedQueryChars", "|{}[]\\"));
        return factory;
    }

}

public class A{
    private B b;
    private int xx;
}
public class B{
    private A a;
    private String xx;
}

If you don't need the B property in the above case, then you can manually add a static keywords to property B when generating

public class A{
    private static B b;
    private int xx;
}
