我正在构建一个SpringBoot应用程序,该应用程序从数据库中加载国际化消息。 (Followed this tutorial)
由此,我必须创建一个ThymeleafConfiguration类并设置一个SpringTemplateEngine Bean。本教程仅给出了有关此配置的粗略想法(仅配置了消息源,但未配置其他模板引擎配置),因此它破坏了我的控制器页面呈现(控制器现在返回字符串而不是视图)。
我正在尝试配置其余的TemplateEngine(例如TemplateResolver,我认为这是渲染不正确的原因),但是,我不知道如何正确进行[我保持收到“模板解析期间发生错误(模板:“ ServletContext资源[/templates/login.html]”)“消息]。
如何正确配置SpringTemplateEngine?
到目前为止,我的配置:
@Configuration
public class ThymeleafConfiguration implements WebMvcConfigurer, ApplicationContextAware{
private ApplicationContext applicationContext;
@Autowired
private DatabaseMessageSource databaseMessageSource;
@Bean
public ViewResolver viewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(thymeleafTemplateEngine());
resolver.setCharacterEncoding("UTF-8");
return resolver;
}
private ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/templates/");
resolver.setSuffix(".html");
resolver.setTemplateMode(TemplateMode.HTML);
return resolver;
}
@Bean
public SpringTemplateEngine thymeleafTemplateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver());
engine.setTemplateEngineMessageSource(databaseMessageSource);
return engine;
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
}
控制器类:
@Controller
public class ApplicationController {
@RequestMapping("/home")
public String home() {
return "/home.html";
}
@RequestMapping("/core/index")
public String index() {
return "/core/index.html";
}
@RequestMapping("/login")
public String login() {
return "login";
}
答案 0 :(得分:1)
问题出在
private ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/templates/"); // Here!!!
resolver.setSuffix(".html");
return resolver;
}
由于模板位于src / main / resources中,因此必须将其指向类路径,如下所示:
@Bean
public SpringResourceTemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("classpath:/templates/"); // It works after adding 'classpath:'
resolver.setSuffix(".html");
return resolver;
}
此外,从接口到实现类的变化不大,应该不会干扰结果。
