我刚刚使用 Spring MVC 3.2.3 和 Spring Security 3.2.1 将所有 xml 配置文件转换为 JavaConfig。我遇到了一些问题，其中成员用 @ElementCollection(fetch=FetchType.EAGER) 注释的实体仍然没有被提取(我的 XML 配置没有这个问题)，我必须添加 @Fetch(FetchMode) .JOIN)注释。但是，我在从 Controller 检索数据时仍然遇到问题。
我的许多请求都由后端完全处理，但是当它们从我的 Controller 方法返回时，我收到错误“HTTP 状态 500 - 无法解析名称为 ' 的 servlet 中名称为 'xxx' 的 View 调度员”。问题是，我只有 3 个 View :登录、索引和管理。索引页是一个单页站点，它对 Controller 进行大量 AJAX 调用，其中大多数使用 @RequestBody 将 JSON 请求解码到 DTO，所有这些都直接使用 @ResponseBody 写入响应，并使用 Jackson 转换为 JSON。这在过去一直有效—— Controller 方法实际上应该只是 REST 端点，但现在，调度程序 servlet 希望将 View 与我的几乎所有请求(但不是全部)关联起来。我不确定如何告诉 View 解析器或调度程序 servlet 仅将索引、管理和登录视为 View ，而将其他所有内容视为简单的 REST 请求。任何帮助，将不胜感激!这是我的配置:
根配置:
@Configuration
@ComponentScan(value = "x.configuration", excludeFilters = @Filter(type = FilterType.ASSIGNABLE_TYPE, value = RootConfig.class))
public class RootConfig {}
安全初始化器:
public class SecurityInitializer extends AbstractSecurityWebApplicationInitializer {}
Web 应用程序初始化器:

@ComponentScan(basePackages = "x.clients")
public class SpringMvcConfig extends WebMvcConfigurerAdapter {

我的所有 Controller 方法都是通过 URL 模式/rest//访问的。
以下 Controller 仅返回枚举项的列表并且工作正常:
@Controller
@RequestMapping("/swterms")
public class SwTermsController {
@RequestMapping(value = "/getSensorTypes", method = RequestMethod.GET)
@ResponseBody
public List<String> getSensorTypes() {
List<String> sensorTypes = new ArrayList<String>();
for (SensorTypes sensorType : SensorTypes.values()){
sensorTypes.add(sensorType.getURI());
}
return sensorTypes;
}
}
该 Controller 返回 map 图层列表。我可以在 Debug模式下单步执行，一切都构建得很好，但它会产生 500 错误:
@Controller
@RequestMapping("/map")
public class MapLayerController {
@Autowired
@Resource(name="mapLayers") private List<OpenLayersMapLayer> mapLayers;
@RequestMapping(value = "/getLayerData", method = RequestMethod.GET)
@ResponseBody
public Map getMapLayers() {
Map model = new HashMap();
model.put("layers", this.mapLayers);
return model;
}
}

最佳答案
尝试删除此行:
viewResolver.setViewNames(new String[] {"login", "index", "admin"});
这导致 viewResolver 忽略 ["login","index","admin"] 中不存在的所有内容
摘自文档:
setViewNames
public void setViewNames(String[] viewNames) Set the view names (or name patterns) that can be handled by this ViewResolver. View names can contain simple wildcards such that 'my*', '*Report' and 'Repo' will all match the view name 'myReport'.
关于java - Spring 3.2 - 切换到 JavaConfig 后无法解析 View 名称，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22285234/
