Spring 在 REST API 上僅調用 404
[英]Spring Boot 404 on REST API calls only
問題描述
問題：
我正在開發需要部署在 tomcat（WAR 文件）上的 Spring-Boot Web 應用程序。 When running the application as Java (right click application.java file and run as Java in Eclipse) or running via mvnw.cmd spring-boot:run, everything works PERFECTLY (home page shows, all CRUD operations work).
When I export a WAR file and deploy to tomcat, my static web content and homepage still load fine, but any API calls return a 404 response.
該項目是使用 Spring Initializr 創建的。 我嘗試通過 Eclipse 戰爭導出和 mvnw.cmd package 導出。 將 WAR 文件放在服務器上的 webapps 目錄中並運行。
目錄結構：
申請文件：
package com.blank.systemshare;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SystemshareApplication {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
}
Servlet初始化器：
package com.blank.systemshare;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

2 個解決方案
解決方案1
1 2020-04-21 20:55:40
刪除 ServletInitializer.java class 並將我的應用程序文件更新為以下解決了該問題（擴展 SpringBootServletInitializer 並覆蓋配置方法）。 請注意，我之前嘗試過，但是使用 Eclipse 和 InteliJ 構建了應用程序。 兩次仍然出現相同的問題。 我最后一次使用mvnw package ，並且在目標目錄中生成的 WAR 工作正常。
package com.blank.systemshare;
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 SystemshareApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

嘗試server.servlet.context-path而不是server.servlet.contextPath 。
