我正在开发一个带有百里香的简单servlet,它可以通过按下按钮来更改文本。
问题是,当我在Spring工具套件4.4中将其作为Spring应用程序运行时,它可以工作,但是当将其编译为servlet并将其上传到tomcat服务器时,会出现此错误:
代码在这里:
MainController.java
package com.example.demo;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class MainController {
@GetMapping("/saludo")
public String saludo(Model model) {
model.addAttribute("saludo", "bondia");
return "index";
}
@GetMapping("/nosaludo")
public String nosaludo(Model model) {
model.addAttribute("saludo", "no te salud");
return "index";
}
@GetMapping("/despido")
public String despido(Model model) {
model.addAttribute("saludo", "Adeu");
return "index";
}
}
ServletInicializer.java
package com.example.demo;
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(CreantServletApplication.class);
}
}

<body>
<form action="./saludo">
<input type="submit" value="Saludar">
</form>
<form action="./nosaludo">
<input type="submit" value="No saludar">
</form>
<form action="./despido">
<input type="submit" value="Despedirse">
</form>
<h1 th:text="${saludo}">Text que es modificara</h1>
</body>
</html>

请发布您的完整请求网址。如果使用war文件将其部署在Tomcat中,则需要将上下文根添加到url。
默认为:
http://<host><port>/<war-name-without-file-type>/saludo
