SpringBoot报错 Error parsing HTTP request header

使用SpringToolSuite4执行Stringboot插入操作时，报请求头错误，具体信息如下

Error parsing HTTP request header
Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level
java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

大致意思是，我的请求信息里包含了非法字符，我的参数如下：显而易见，包含了“#{}”非法字符

原因找到了，那我们就来解决它

上网查了一些资料，解决方法有很多，比较容易理解的2种方案

1、降低Tomcat版本：不推荐

2、增加Tomcat配置类：可以插入\"#<>[\\]^`{|}中的任意特殊字符，当然也可以自定义

package com.xkcoding.rbac.security.config;
import org.apache.catalina.connector.Connector;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class TomcatConfig {
    @Bean
    public TomcatServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((Connector connector) -> {
                connector.setProperty("relaxedPathChars", "\"#<>[\\]^`{|}");
                connector.setProperty("relaxedQueryChars", "\"#<>[\\]^`{|}");
        });
        return factory;
    }
}

此时，问题已解决，且测试成功
