SpringBoot2.1.3修改tomcat参数支持请求特殊符号

最近遇到一个问题，比如GET请求中，key,value中带有特殊符号，请求会报错，见如下URL：

http://xxx.xxx.xxx:8081/aaa?key1=val1&a.[].id=123&b=a[1]

现在，我们进入boot启动类，添加如下代码即可：

public class DemoApp {

public static void main(String[] args) {

SpringApplication.run(DemoApp.class, args);

}

@Bean

public TomcatServletWebServerFactory webServerFactory() {

TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();

factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {

@Override

public void customize(Connector connector) {

connector.setProperty("relaxedPathChars", "\"<>[\\]^`{|}");

connector.setProperty("relaxedQueryChars", "\"<>[\\]^`{|}");

}

});

return factory;

}

}
