我想在我的web应用中使用Thymeleaf作为模板引擎。我在Google上搜索到用struts2配置Themeleaf，发现一些解决方案有一个plugin。我在我的应用程序中配置了插件，但我无法使用插件呈现页面。而是我得到错误：Struts 2 with Thymeleaf

这是落实DefaultTemplateEngineProvider.java

private String suffix = ".html";
private boolean cacheable = true;
// Default template cache TTL to 1 hour. If not set, entries would live in
// cache until expelled by LRU.
private Long cacheTtlMillis = 3600000L;
private TemplateEngine templateEngine;
/**
* Configure settings from the struts.xml or struts.properties, using sensible
* defaults if values are not provided.
*/
public void configure() {
ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
templateResolver.setTemplateMode(templateMode);
templateResolver.setCharacterEncoding(characterEncoding);
templateResolver.setPrefix(prefix);
templateResolver.setSuffix(suffix);
templateResolver.setCacheable(cacheable);
templateResolver.setCacheTTLMs(cacheTtlMillis);
templateEngine = new TemplateEngine();
templateEngine.setTemplateResolver(templateResolver);
templateEngine.setMessageResolver(new StrutsMessageResolver());
}
public TemplateEngine get() {
if (templateEngine == null) {
configure();
}
return templateEngine;
}
@Inject(value = "struts.thymeleaf.templateMode", required = false)
public void setTemplateMode(String templateMode) {
this.templateMode = templateMode;
}
@Inject(value = "struts.thymeleaf.encoding", required = false)

this.characterEncoding = characterEncoding;

}
}
我已经写了自定义的结果集，并在官方网站的文件配置Thymeleaf。但得到同样的错误。
我的自定义结果类型为
public class ThymeleafResult implements Result {
private String defaultEncoding = "UTF-8";
private TemplateEngineProvider templateEngineProvider;
private String templateName;
/**
* The result parameter name to set the name of the template to.
* <p/>
* IMPORTANT! Struts2 will look for this field reflectively to determine which
* parameter is the default. This allows us to have a simplified result
* configuration. Don't remove it!
*/
public static final String DEFAULT_PARAM = "templateName";
public ThymeleafResult() {
}
public ThymeleafResult(String templateName) {
this.templateName = templateName;
}
public void execute(ActionInvocation actionInvocation) throws Exception {
TemplateEngine templateEngine = templateEngineProvider.get();
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
ServletContext servletContext = ServletActionContext.getServletContext();
Object action = actionInvocation.getAction();
StrutsContext context = new StrutsContext(request, response, servletContext, action);
response.setContentType("text/html");
response.setCharacterEncoding(defaultEncoding);
System.out.println(templateName);
templateEngine.process(templateName, context, response.getWriter());
}
@Inject(StrutsConstants.STRUTS_I18N_ENCODING)
public void setDefaultEncoding(String defaultEncoding) {
this.defaultEncoding = defaultEncoding;
}
@Inject
public void setTemplateEngineProvider(TemplateEngineProvider templateEngineProvider) {
this.templateEngineProvider = templateEngineProvider;
}
public void setTemplateName(String templateName) {
this.templateName = templateName;
}
而且struts.xml的是
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<constant name="struts.multipart.maxSize" value="1000000000" />
<constant name="struts.custom.i18n.resources" value="ApplicationResources" />
<bean type="org.codework.struts.plugins.thymeleaf.spi.TemplateEngineProvider" name="default" class="org.codework.struts.plugins.thymeleaf.spi.DefaultTemplateEngineProvider" />
<package name="default" namespace="/" extends="struts-default">
<result-types>
<result-type name="thymeleaf" class="org.codework.struts.plugins.thymeleaf.ThymeleafResult"/>
</result-types>
<default-action-ref name="home"></default-action-ref>
<action name="home" class="com.demo.example.Welcome">
<result name="success" type="thymeleaf">/WEB-INF/templates/hello.html</result>
</action>
</package>
</struts>
你能告诉我们你的代码以及你如何配置它来运行，而不仅仅是错误吗？ （更多，因为我懒得阅读文档比其他任何东西） –
检查模板文件的位置，Struts把他们的模板放在资源下。 –
@ShotgunNinja我已添加更多详情。请检查我做错了什么。 –
