java中Spring boot如何设置freemarker模板路径

1、spring boot中使用freemarker模板引擎技术，spring boot中提供了一些默认的配置。默认配置如下所示：本文只探羲耶笸砻讨freemarker中模板路径的设置方式，其他配置，请注意查看后续文章。图中代码如下（图片只是为了查看方便）：# FREEMARKER (FreeMarkerAutoConfiguration)spring.freemarker.allow-request-override=false # Set whether HttpServletRequest attributes are allowed to override (hide) controller generated model attributes of the same name.spring.freemarker.allow-session-override=false # Set whether HttpSession attributes are allowed to override (hide) controller generated model attributes of the same name.spring.freemarker.cache=false # Enable template caching.spring.freemarker.charset=UTF-8 # Template encoding.spring.freemarker.check-template-location=true # Check that the templates location exists.spring.freemarker.content-type=text/html # Content-Type value.spring.freemarker.enabled=true # Enable MVC view resolution for this technology.spring.freemarker.expose-request-attributes=false # Set whether all request attributes should be added to the model prior to merging with the template.spring.freemarker.expose-session-attributes=false # Set whether all HttpSession attributes should be added to the model prior to merging with the template.spring.freemarker.expose-spring-macro-helpers=true # Set whether to expose a RequestContext for use by Spring's macro library, under the name "springMacroRequestContext".spring.freemarker.prefer-file-system-access=true # Prefer file system access for template loading. File system access enables hot detection of template changes.spring.freemarker.prefix= # Prefix that gets prepended to view names when building a URL.spring.freemarker.request-context-attribute= # Name of the RequestContext attribute for all views.spring.freemarker.settings.*= # Well-known FreeMarker keys which will be passed to FreeMarker's Configuration.spring.freemarker.suffix= # Suffix that gets appended to view names when building a URL.spring.freemarker.template-loader-path=classpath:/templates/ # Comma-separated list of template paths.spring.freemarker.view-names= # White list of view names that can be resolved.

3、此种配置，只能读取classpath下的路径。如果想要读取其他路径则要重写freemarker的默认配置，在spring boot中，你可以这样做：图中代码如下（图片只是为了查看方便）：@Configurationpublic class TemplateLoader 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 { FreeMarkerConfigurer configurer = new FreeMarkerConfigurer(); configurer.setTemplateLoaderPaths("file:绝对路径","http://www.xxx.com/"); configurer.setDefaultEncoding("UTF-8"); return configurer; }}
