我尝试通过一个简单的Sping Boot 和FreeMarker集成的例子(基于我在网上找到的教程),由于某种原因,我的视图没有被解析到FreeMarker模板(我认为这是问题所在)。
在浏览器中启动时的结果只是返回TFL视图文件的名称iIndieE.“Index”。因此控制器正在被调用并返回字符串“Index”,但似乎没有触发器拉入FTL文件本身。任何帮助都将不胜感激...
我有下面的配置类,我在其中定义了视图解析器和免费制造商配置。
@Configuration
public class MvcConfigurer extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
resolver.setPrefix("");
resolver.setSuffix(".ftl");
resolver.setContentType("text/html; charset=UTF-8");
return resolver;
}
@Bean
public FreeMarkerConfigurer freemarkerConfig() throws IOException, TemplateException {
FreeMarkerConfigurationFactory factory = new FreeMarkerConfigurationFactory();
factory.setTemplateLoaderPaths("classpath:templates", "src/main/resource/templates");
factory.setDefaultEncoding("UTF-8");
FreeMarkerConfigurer result = new FreeMarkerConfigurer();
result.setConfiguration(factory.createConfiguration());
return result;
}
}
然后我有下面的控制器:
@RestController
public class HelloController {
/**
* Static list of users to simulate Database
*/
private static List<User> userList = new ArrayList<User>();
//Initialize the list with some data for index screen
static {
userList.add(new User("Bill", "Gates"));
userList.add(new User("Steve", "Jobs"));
userList.add(new User("Larry", "Page"));
userList.add(new User("Sergey", "Brin"));
userList.add(new User("Larry", "Ellison"));
}
/**
* Saves the static list of users in model and renders it
* via freemarker template.
*
* @param model
* @return The index view (FTL)
*/
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index(@ModelAttribute("model") ModelMap model) {
model.addAttribute("userList", userList);
return "index";
}
/**
* Add a new user into static user lists and display the
* same into FTL via redirect
*
* @param user
* @return Redirect to /index page to display user list
*/
@RequestMapping(value = "/add", method = RequestMethod.POST)
public String add(@ModelAttribute("user") User user) {
if (null != user && null != user.getFirstname()
&& null != user.getLastname() && !user.getFirstname().isEmpty()
&& !user.getLastname().isEmpty()) {
synchronized (userList) {
userList.add(user);
}
}
return "redirect:index.html";
}
}
最后,我将以下FTL文件存储在“src/main/resource/templates”中
<html>
<head><title>ViralPatel.net - FreeMarker Spring MVC Hello World</title>
<body>
<div id="header">
<H2>

</div>
<div id="content">

<legend>Add User</legend>
<form name="user" action="add.html" method="post">

Lastname: <input type="text" name="lastname" /> <br/>
<input type="submit" value=" Save " />
</form>
</fieldset>
<br/>
<table class="datatable">
<tr>
<th>Firstname</th> <th>Lastname</th>

<#list model["userList"] as user>
<tr>

</tr>
</#list>

</div>
</body>

问题是你的控制器有错误的注解,你应该使用
@Controller
代替@RestController
@RestController
用来告诉你的控制器发来的响应应该发到浏览器,通常是一个Map到json的对象,和添加@ResponseBody
是一样的。cbwuti442#
虽然你刚刚得到了答案。但是,你的帖子有两点。
首先,在Sping Boot 中配置Freemarker模板非常简单。不需要使用WebMvcConfigurerAdapter。您只需要将您的属性放在您的类路径中,内容如下
第二,@Controller被用来标注类作为Spring MVC控制器。@RestController标注的类与@Controller相同,但是处理程序方法上的@ResponseBody是隐含的。所以在您的情况下必须使用@Controller。
