我有控制器映射/user和/order：

@RestController
@RequestMapping("/users")
public class UserController {
    ...
}
@RestController
@RequestMapping("/orders")
public class OrderController {
    ...
}

我想分别通过URL http://localhost:8080/api/users 和来访问它们http://localhost:8080/api/orders。

如何在Spring Boot" title="Spring Boot">Spring Boot中实现这一目标？

回答：

你可以/api/*在自定义配置中提供到Spring Boot应用程序的根上下文路径的映射。

import org.springframework.boot.autoconfigure.web.DispatcherServletAutoConfiguration;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.DispatcherServlet;
@Configuration
public class DispatcherServletCustomConfiguration {
    @Bean
    public DispatcherServlet dispatcherServlet() {
        return new DispatcherServlet();
    }
    @Bean
    public ServletRegistrationBean dispatcherServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(
                dispatcherServlet(), "/api/");
        registration.setName(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_REGISTRATION_BEAN_NAME);
        return registration;
    }
}
