我正在尝试将Apache Tiles添加到我正在玩的简单的Spring MVC webapp中，我似乎无法让它工作（它没有Tiles工作）。我做出的任何请求都会返回400个错误请求，日志中没有任何内容出现（甚至设置为DEBUG）所以我不确定从哪里开始debbuging。据我所知，Controller map方法永远不会被调用，因为那里有登录而且它没有出现在日志中（在此之前我会从Spring获得大量关于在它之前解析映射到控制器的调试信息）实际上被称为 - 现在没有出现。）
我的配置文件如下（全部在/ WEB-INF /下）： web.xml中：

布局只包含一个包含标签的每个部分的div。所有视图都包含简单的代码，如标题或div。
对于控制器 ProductController.java：
@Controller
@RequestMapping("/product")
public class ProductController {
protected Logger logger = Logger.getLogger(getClass());
@Autowired
private ProductService productService;
@RequestMapping(value = "/{id}", method = RequestMethod.GET)
public ModelAndView getProduct(@PathVariable Long id) {
logger.info("GET product " + id);
Product product = productService.find(id);
ModelAndView mv = new ModelAndView("product_detail", "product", product);
return mv;
}
}
使用maven嵌入式tomcat插件部署它并转到localhost：8080 / myapp / product / 1只提供HTTP 400代码而没有任何其他迹象表明出现了问题。数据库中有一个带有该ID的产品，来自控制器的所有产品都可以工作，就像我在添加瓷砖之前尝试过的那样。
很抱歉代码丢失，但我现在无法让它工作一段时间，我不知道还有什么可以尝试或从哪里开始调试。
是否有某种方法可以强制记录返回400错误请求时的问题？
答案 0 :(得分：0)
您在servlet配置中缺少对myapp-servlet.xml的引用。
