如何为Spring MVC webapp添加Freemarker支持？依赖问题？

Question

我正在尝试使用Freemarker和Java配置创建Spring MVC应用程序.

我习惯使用JSP,但我想我会给Freemarker一个旋转.

我添加了Freemarker作为依赖,并且Maven正在下载jar:

        <dependency>
        <groupId>org.freemarker</groupId>
        <artifactId>freemarker</artifactId>
        <version>2.3.20</version>
    </dependency>

我正在尝试使用3.2.3.RELEASE版本的Spring.

我的MVC配置,通过阅读类似问题组装而成:

@ComponentScan(basePackages="yhj.*")
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{


@Bean
public ViewResolver viewResolver() {
    FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
    resolver.setCache(true);
    resolver.setPrefix("");
    resolver.setSuffix(".ftl");
    return resolver;

}

@Bean
public FreeMarkerConfigurer freemarkerConfig() {
    FreeMarkerConfigurer result = new FreeMarkerConfigurer();
    result.setTemplateLoaderPath("/WEB-INF/views/");
    return result;

}
}

当我尝试运行它时,我得到一个编译错误,我的IDE告诉我无法解析方法'setTemplateLoaderPath(String)'.

那么......看起来像是使用Freemarker配置Spring MVC的正确方法吗？如果这是问题,我需要添加到我的POM的依赖项是什么？

Answer 1

我的Spring Boot 1.0.2,Spring 4.0.3和FreeMarker 2.3.20的解决方案是以下类:

@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.setTemplateLoaderPath("classpath:templates");
    factory.setDefaultEncoding("UTF-8");
    FreeMarkerConfigurer result = new FreeMarkerConfigurer();
    result.setConfiguration(factory.createConfiguration());
    return result;
  }
}

此外,您需要pom.xml在问题和DaFoot自己的答案中进行相同的更改.

好吧,我已经对编译问题进行了排序,为我的pom添加了一个依赖...

    <dependency><!-- needed for freemarker FreeMarkerConfigurer stuff -->
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>${spring.version}</version>
    </dependency>

@Bean(name = "freeMarkerViewResolver")
    public FreeMarkerViewResolver getFreeMarkerViewResolver() { 
        FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
        resolver.setPrefix("/WEB-INF/views/json/");
        resolver.setSuffix(".json");
        resolver.setOrder(2);
        resolver.setContentType("application/json");
        resolver.setCache(true);
        return resolver;
    }

    @Bean(name = "freemarkerConfig")
    public FreeMarkerConfigurer getFreemarkerConfig() throws IOException, TemplateException { 
        FreeMarkerConfigurer result = new FreeMarkerConfigurer();
        result.setTemplateLoaderPaths("/"); // prevents FreeMarkerConfigurer from using its default path allowing setPrefix to work as expected
        return result;
    }
