Java 为什么项目名称出现在我的GET请求中

我有用Java/Spring MVC编写的测试代码.我想运行它，并期望我的GET请求如下所示:

localhost:9090/hello 

但我明白了

localhost:9090/spring-mvc-app1/hello

我把这个项目命名为spring-mvc-app1，但我不明白为什么这个名字会出现在逻辑上不应该出现的地方.开发环境--Eclipse.

The code itself:个

package john.project.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class ControllerOrder {
    @GetMapping("/hello")
    public String helloPage() {
        return "order/hello";
    }
    
    @GetMapping("/goodbye")
    public String goodbyePage() {
        return "order/goodbye";
    }
}

Config: SpringConfig.java:个

package john.project.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.thymeleaf.spring6.SpringTemplateEngine;
import org.thymeleaf.spring6.templateresolver.SpringResourceTemplateResolver;
import org.thymeleaf.spring6.view.ThymeleafViewResolver;


@Configuration
@ComponentScan("john.project")
@EnableWebMvc
public class SpringConfig implements WebMvcConfigurer {

    private final ApplicationContext applicationContext;

    @Autowired
    public SpringConfig(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
    }

    @Bean
    public SpringResourceTemplateResolver templateResolver() {
        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setApplicationContext(applicationContext);
        templateResolver.setPrefix("/WEB-INF/views/");
        templateResolver.setSuffix(".html");
        return templateResolver;
    }

    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.setEnableSpringELCompiler(true);
        return templateEngine;
    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine());
        registry.viewResolver(resolver);
    }
}

SpringMvcDispatcherServletInitializer.java:个

package john.project.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{SpringConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}
