【问题描述】：
我的网络应用程序在 Eclipse Photon STS、java 8 和 Spring Boot 2.02 上运行良好，并使用端点嵌入了 tomcat：
http://localhost:8081/DataViewer/tspsPatentSearch
但是当我将代码编译成 DataViewer.war 文件（使用 mvn 包）并在 Linux 上的 Tomcat 9 上运行它时 带端点：
http://myserver.com:8081/DataViewer/tspsPatentSearch
我知道臭名昭著：
Whitelabel Error Page
There was an unexpected error (type=Not Found, status=404).
/DataViewer/tspsPatentSearch
我的 pom.xml 文件是：

<description>TSPS data viewer</description>
在 application.properties 我有：
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
server.servlet.path=/DataViewer
我的主要课程是：
package com.clarivate.dataviewer;
import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.LogManager;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class DvMain extends SpringBootServletInitializer {
static Logger logger = LogManager.getRootLogger();
public static void main(String[] args) {
logger.debug("DS1A in main()");
SpringApplication.run(DvMain.class, args);
logger.info("DS1C finished.");
}
//@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(DvMain.class);
}
}
我的 MainController.java 有：
@GetMapping("/tspsPatentSearch")
public String tspsPatentSearch(Model model) {
model.addAttribute("tspsPatent", new TspsPatent());
return "tspsPatentSearch";
}
war 文件解压正常，没有错误。在 catalina.out 我们有：
2018-10-04 12:09:09.954 INFO 12950 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/tspsPatentSearch],methods=[POST]}" onto public java.lang.String com.clarivate.dataviewer.controller.MainController.tspsPatentSearch(com.clarivate.dataviewer.model.TspsPatent,org.springframework.ui.Model,org.springframework.validation.BindingResult)
并且没有错误。我试过this 即我的包结构是正确的，this 即我的 jsp 位于正确的位置 (data_viewer\src\main\webapp\WEB-INF\jsp) 我现在没有想法了。非常感谢任何帮助
编辑：如果我将 tspsPatentSearch.jsp 复制到 war 文件的顶级目录中，则 tomcat 会找到它。所以看起来tomcat忽略了：
spring.mvc.view.prefix=/WEB-INF/jsp/
或根本找不到 application.properties。
【问题讨论】：
-
试试
http://localhost:8081/tspsPatentSearch -
谢谢，我刚刚尝试了这两个端点，我得到了同样的 404 错误
-
您能否发布完整的 DvMain 类，包括所有导入
-
@kj007 我已经更新了我原来的帖子
