springboot (four) - solve the problem that Springboot GET request parameters are too long

Many answers to this question on the Internet are to modify the Tomcat configuration file, but we are a springboot project, and Tomcat is built-in, so simply modifying the Tomcat configuration file is useless. It only takes a very simple piece of code to solve this problem.

Pay attention to my main class

@SpringBootApplication
public class Application {
    
    

    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
    
    
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers(
                (TomcatConnectorCustomizer) connector -> connector.setProperty("relaxedQueryChars", "|{}[]\\")
        );
        return factory;
    }
    public static void main(String[] args){
    
    
        SpringApplication.run(Application.class, args);
    }
}

Just add the following code in the main class and it will be fine

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