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
org.apache.coyote.http11.AbstractHttp11Processor process

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
