案例

文档

使用说明

通过 @Controller @RestController 配置控制器

//@Controller
@RestController
@RequestMapping("/users")
public class IndexController {
    
}

配置请求

@GET("index")
@POST("post")
@PUT("articles/{id}")
......
@RequestMapping("/users/{id}")
@RequestMapping(value = "/users/**", method = {RequestMethod.GET})
@RequestMapping(value = "/users/*.html", method = {RequestMethod.GET})
@RequestMapping(value = {"/index.action", "/index.do", "/index"}, method = RequestMethod.GET)
@Interceptor({LoginInterceptor.class, ...})
public (String|List<?>|Set<?>|Map<?>|void|File|Image|...) \\w+ (request, request, session,servletContext, str, int, long , byte, short, boolean, @Session("loginUser"), @Header("User-Agent"), @Cookie("JSESSIONID"), @PathVariable("id"), @RequestBody("users"), @Multipart("uploadFiles") MultipartFile[]) {
    service...
    return </>;
}

自定义参数转换器

@ParameterConverter 
public class DateConverter implements Converter<String, Date> {
    @Override
    public Date doConvert(String source) throws ConversionException {
        ...
    }
}

也可以通过xml文件配置简单视图,静态资源,自定义视图解析器,文件上传解析器,异常处理器,参数解析器

登录实例

@Controller
public class UserController {

/* 
    <controller prefix="/WEB-INF/view/" suffix=".ftl">
        <action resource="login" name="login" />
        <action resource="register" name="register" />
    </controller> */
    
    // @GET("login")
    @RequestMapping(value = "/login" , method = RequestMethod.GET)
    public String login() {
        return "/login/login";//支持jsp,FreeMarker,Thymeleaf,自定义视图
    }
    
    @Logger("登录")
    //@POST("/login")
    //@RequestMapping(value = "/login" , method = RequestMethod.POST)
    @ActionMapping(value = "/login", method = RequestMethod.POST)
    public String login(HttpSession session, RedirectModel redirectModel, @Valid User user, Errors error) {
    
        if (error.hasErrors()) {
            System.err.println(error.getAllErrors());
            redirectModel.attribute("msg", error.getAllErrors().toString());
            return "redirect:/login";
        }
    
        User login = userService.login(user);
        if (login == null) {
            redirectModel.attribute("userId", user.getUserId());
            redirectModel.attribute("msg", "登录失败");
            return "redirect:/login";
        }
        redirectModel.attribute("msg", "登录成功");
        session.setAttribute(USER_INFO, login);
        return "redirect:/user/info";
    }
    
}

文件下载,支持直接返回给浏览器图片

@RequestMapping(value = {"/download"}, method = RequestMethod.GET)
public File download(String path) {
    return new File(path);
}
@GET("/display")
public final BufferedImage display(HttpServletResponse response) throws IOException {
    response.setContentType("image/jpeg");
    return ImageIO.read(new File("D:/taketoday.cn/webapps/upload/logo.png"));
}

@GET("captcha")
public final BufferedImage captcha(HttpServletRequest request) throws IOException {
    BufferedImage image = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, BufferedImage.TYPE_INT_RGB);
    Graphics graphics = image.getGraphics();
    graphics.setColor(Color.WHITE);
    graphics.fillRect(0, 0, IMG_WIDTH, IMG_HEIGHT);
    Graphics2D graphics2d = (Graphics2D) graphics;
    drawRandomNum(graphics2d, request);
    return image;
}

文件上传,支持多文件

@RequestMapping(value = { "/upload" }, method = RequestMethod.POST)
public final String upload(@Multipart MultipartFile uploadFile) throws IOException {

    String upload = "D:/www.yhj.com/webapps/upload/";
    String path = upload + uploadFile.getFileName();
    File file = new File(path);
    uploadFile.save(file);

    return "/upload/" + uploadFile.getFileName();
}

@POST({"/upload/multi"})
public final String multiUpload(HttpServletResponse response, @Multipart MultipartFile[] files) throws IOException {

    String upload = "D:/www.yhj.com/webapps/upload/";
    
    for (MultipartFile multipartFile : files) {
        String path = upload + multipartFile.getFileName();
        File file = new File(path);
        System.out.println(path);
        if (!multipartFile.save(file)) {
            return "<script>alert('upload error !')</script>";
            //response.getWriter().print("<script>alert('upload error !')</script>");
        }
    }
    //response.getWriter().print("<script>alert('upload success !')</script>");
