spring - Spring Boot-多个模板位置

我希望Spring在不同的位置查找模板，而不仅仅是在src/main/resource/templates/中。

我这里有

@Configuration
public class WebConfig{

    @Autowired
    private SpringTemplateEngine templateEngine;

    @PostConstruct
    public void clientTemplate(){
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setPrefix("static/client");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setOrder(templateEngine.getTemplateResolvers().size());
        resolver.setCacheable(false);
        templateEngine.addTemplateResolver(resolver);
    }
}

但是，当我尝试访问/src/main/resources/static/client中的现有模板index.html时，我得到了：

java.lang.IllegalArgumentException: ApplicationContext has not been initialized in resource resolver. TemplateResolver or ResourceResolver might not have been correctly configured by the Spring Application Context.

如何解决这个问题？

最佳答案

1.非Spring管理的SpringResourceTemplateResolver
使用当前设置，您正在创建SpringResourceTemplateResolver的实例，而不是在@Bean方法中。因此，它不会在春季被捡起，您需要提供ApplicationContext（example）：

SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/WEB-INF/templates/");
resolver.setTemplateMode(TemplateMode.HTML);

注意resolver.setApplicationContext(applicationContext);

2. Spring托管的SpringResourceTemplateResolver
您可能会看到不需要这样做的示例，但是它们肯定是在SpringResourceTemplateResolver方法中创建@Bean实例。 Spring将其拾取并为您设置应用程序上下文（example）：

@Bean
public ITemplateResolver templateResolver() {
    SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
    resolver.setPrefix("/WEB-INF/templates/");
    resolver.setSuffix(".html");
    resolver.setTemplateMode(TemplateMode.HTML);
    resolver.setCacheable(false);
    return resolver;
}
