在我的Spring MVC应用程序中,我试图创建一个自定义的百里香方言,以将ASCII字符串转换为文本。我可以用'th'
以外的前缀创建方言。但是,如果我尝试使用'th'
作为前缀,则服务器将引发以下运行时异常。
org.thymeleaf.exceptions.ConfigurationException: When using SpringTemplateEngine, at least one of the configured dialects must be or extend org.thymeleaf.spring4.dialect.SpringStandardDialect.
org.thymeleaf.spring4.SpringTemplateEngine.initializeSpecific(SpringTemplateEngine.java:147)
org.thymeleaf.TemplateEngine.initialize(TemplateEngine.java:831)

javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:842)
javax.servlet.http.HttpServlet.service(HttpServlet.java:847)
基本上,我在这里需要实现的是创建一个像
th:asciitext
这样的自定义方言。任何帮助都感激不尽。注意:如果有人需要研究我已经尝试过的代码,请随时在评论部分询问。
最佳答案
我能找到的唯一方法是扩展SpringTemplateEngine
(它被设计为可扩展的)。之后,用新的模板引擎替换default SpringTemplateEngine
。查看以下代码:
MySpringTemplateEngine
public class MySpringTemplateEngine extends SpringTemplateEngine {
private Set<IProcessor> additionalProcessors;
public Set<IProcessor> getAdditionalProcessors() {
return additionalProcessors;
}
public void setAdditionalProcessors(Set<IProcessor> additionalProcessors) {
this.additionalProcessors = additionalProcessors;
}
@Override
public void afterPropertiesSet() throws Exception {
super.afterPropertiesSet();
Map<String, IDialect> dialectsByPrefix = this.getDialectsByPrefix();
StandardDialect springDialect = (StandardDialect) dialectsByPrefix.get("th");
springDialect.setAdditionalProcessors(additionalProcessors);
}
}
application-context.xml
<bean id="templateEngine" class="path.to.extended.engine.MySpringTemplateEngine">
<property name="templateResolver" ref="templateResolver" />
<property name="additionalProcessors">
<set>
<bean class="path.to.your.processor.AttrProcessor1" />
<bean class="path.to.your.processor.AttrProcessor2" />
</set>
</property>
</bean>
