spring-boot - 在 spring boot 中的请求目标中发现无效字符

Question

我的应用程序以 java -jar 启动，版本为 1.5.6.RELEASE 的 spring boot。
我的请求之一的内容具有字符“{”。当它被发送到服务器时，会引发以下异常:

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 at org.apache.coyote.http11.Http11InputBuffer.parseRequestLine(Http11InputBuffer.java:472) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:683) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:868) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1455) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745)

哪里错了？
我如何解决它？

我的休息是这样的:

var jsonData = {
                    id: $("#hiddenId").val(),
                    permitNumber: $("#txtPermitNumber").val(),
                    permitToDate: $("#txtPermitToDate").val()
               }
document.location = restUrl + "/print?reportParams= " + JSON.stringify(jsonData);

根据 https://tomcat.apache.org/tomcat-8.5-doc/config/systemprops.html , requestTargetAllow 已弃用。对我来说，这里介绍的其他解决方案也不起作用。根据 Tomcat 文档，我找到了一种方法来设置relaxedQueryChars 属性:

@Bean
public ConfigurableServletWebServerFactory webServerFactory() {
    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
    factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
        @Override
        public void customize(Connector connector) {
            connector.setProperty("relaxedQueryChars", "|{}[]");
        }
    });
    return factory;
}
