[英]Tomcat server “HTTP status 404” on Eclipse, working fine on windows
[英]HTTP Status 404 after WAR file deployment on tomcat maven even my project is working fine
當我“以 Spring 啟動應用程序運行”時,我的 spring-boot 項目運行良好,但是當我將它“Maven 安裝”到 WAR 文件時,然后將其部署到 tomcat 錯誤,如源服務器 - >目標資源的當前表示或不願意透露存在的表示。”。 即使我訪問了正確的 URL,正如我在使用“運行為 Spring 啟動應用程序”選項運行它時訪問的一樣(首先使用 WAR 文件名。當然:喜歡:“ Z80791B3AE7002CB88C24687/8xmlFget://localhost,776D9FAA/8xmlFget://localhost:)它仍然是404錯誤。
這是我的 POM 文件

return u;
}
@RequestMapping("/view/{id}")
public Optional<db_url> getbyID(@PathVariable Long id){
return res.findById(id);
}
@RequestMapping(method=RequestMethod.PUT, value="/update/{id}")
public void update(@RequestBody db_url detail, @PathVariable Long id) {
res.save(detail);
}
@RequestMapping(method=RequestMethod.DELETE, value="/delete/{id}")
public void delete(@PathVariable Long id) {
res.deleteById(id);
}
}
我猜你的應用程序在你的 IDE 上運行時運行正常!
建議在您的pom.xml
文件中添加<fileName>
。
<build>
<finalName>app-name</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
現在,當您執行maven clean
和maven package
時,目標目錄中將有一個帶有您提供的名稱的 war 文件。
您可以將其移動到 tomcat 安裝中的webapp
目錄並啟動服務器。
現在,當您在應用程序中訪問 REST 調用時,您必須按如下方式調用它們!
localhost:8088/app-name/first/get/call
您必須在 rest 調用中包含戰爭文件名 ( app-name
)。
希望這可以幫助!
祝你好運!!
