Question

这是Spring的初始化程序。我没有使用任何.xml文件。

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;

@Configuration
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{
                WebAppConfig.class,
                SecurityConfig.class,
                DatabaseConfig.class,
                DataSourceGenerator.class,
                QuartzConfig.class,
                QueueConfig.class
        };
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.addFilter(
                "facilityFilter", new FacilityServletFilter()
        ).addMappingForUrlPatterns(null, false, "/api/*");

        servletContext.addFilter(
                "hmacFilter", new HmacFilter()
        ).addMappingForUrlPatterns(null, false, "/api/*");
    }

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

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }
}

这是我的控制员之一。

@Controller
@RequestMapping(value = "/install")
public class HelloController {

    @RequestMapping(value = "/hi", method = RequestMethod.GET,
            consumes = "*/*", produces = "text/html")
    public String sayHello(){
        return "<html> <head> <title>API</title>" +
                "</head>        <body>        <h1>Welcome to the Eric</h1>" +
                "</body>        </html>";
    }

}

我的所有其他控制器似乎都能正常工作，但是当我尝试命中端点时，这个控制器会返回404错误。当我通过Postman调用它时，代码在调试器中被命中。

Answer 1

将@ResponseBody添加到您的控制器方法，否则spring会尝试搜索名为"<html> <head> <title>API</title>..."

的视图

@Controller
@RequestMapping(value = "/install")
public class HelloController {

    @RequestMapping(value = "/hi", method = RequestMethod.GET, consumes = "*/*", produces = "text/html")
    @ResponseBody
    public String sayHello(){
        return "<html> <head> <title>API</title>" +
                "</head>        <body>        <h1>Welcome to the Eric</h1>" +
                "</body>        </html>";
    }

}

Answer 2

根据Raplh的建议，您可以这样做但如果您计划更多这些方法，那么只需将@Controller替换为@RestController

控制器寄存器，但在返回数据时获得404
