最近在切换旧的spring项目到springboot,顺便把服务器换成tomcat.

在测试中发现报错,查了一下发现

错误原因：

当在浏览器中访问时 URL中带有特殊字符，如花括号冒号时，就会出现这个错误。

例如：http://local:80/index.do?{id:123}

解决方法：

1、去除URL中的特殊字符；

3、使用 Post 方法提交数据

4、更换低版本的Tomcat来规避这种问题。

5、在 conf/catalina.properties  添加或者修改： 

　　5.1  添加  tomcat.util.http.parser.HttpParser.requestTargetAllow=|{} 

5.2  修改tomcat/conf/catalina.properties的配置文件 
Tomcat在 7.0.73, 8.0.39, 8.5.7 版本后，添加了对于http头的验证。 
具体来说，就是添加了些规则去限制HTTP头的规范性 
org.apache.tomcat.util.http.parser.HttpParser#IS_NOT_REQUEST_TARGET[]中定义了一堆not request target 
if(IS_CONTROL[i] || i > 127 || i == 32 || i == 34 || i == 35 || i == 60 || i == 62 || i == 92 || i == 94 || i == 96 || i == 123 || i == 124 || i == 125) { 
IS_NOT_REQUEST_TARGET[i] = true; 
} 
 

但是我们现在设置的是springboot集成的tomcat,没办法去改文件.所以呢

设置属性来解决RelaxedQueryChars属性

 解决问题如下：

/**
 * 解决异常信息：
 *  java.lang.IllegalArgumentException:
 *      Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
 * @return
 */
@Bean
public ConfigurableServletWebServerFactory webServerFactory() {
    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
    factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
        @Override
        public void customize(Connector connector) {
            connector.setProperty("relaxedQueryChars", "|{}[]");//给所有链接添加这个属性
        }
    });
    return factory;
}       
解决啦~~
