我正在開發一個彈簧支架控制器。但是，當我嘗試訪問 url ( http://localhost:8080/customer-crm/api/customer ) 時，它不起作用并給出 404 not find 。但對于根“/”，它工作正常并給出index.jsp頁面這是AppConfiguration.class：package com.customer.crm.configuration;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.ViewResolver;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import org.springframework.web.servlet.view.InternalResourceViewResolver;import org.springframework.web.servlet.view.JstlView;@Configuration@EnableWebMvc@ComponentScan(basePackages = "com.customer.crm")public class AppConfiguration {    @Bean    public ViewResolver viewResolver() {        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();        viewResolver.setViewClass(JstlView.class);        viewResolver.setPrefix("/WEB-INF/views/");        viewResolver.setSuffix(".jsp");        return viewResolver;    }}這是Index.class控制器：package com.customer.crm.rest;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import com.customer.crm.entity.Customer;@RestController@RequestMapping("/api")public class Index {    @RequestMapping(value = "/customer", method = RequestMethod.GET)    public Customer getIndex() {        System.out.println("executing in index controller");        Customer customer = new Customer("Mike", "John", "[email protected]");        return customer;    }甚至連消息也getIndex()沒有打印出來。我嘗試清理項目并清理 tomcat 目錄，但沒有任何改變。誰能告訴我問題出在哪里？
