springboot整合freemarker自动加载宏

springboot引入freemarker最大的问题，在于springboot的application.properties配置文件，不能覆盖所有的freemarker配置

如果freemarker有自定义宏应该怎样引入呢？

首先 application.properties增加配置（与freemarker.properties一样）

auto_import = _
auto_include = /layout/pageShow.html

然后增加FreemarkerConfig类，启动即可

/** * Freemarer 配置 * 增加自动注入和包含配置 * Created by 灰灰 on 2017/7/1. */@org.springframework.context.annotation.Configurationpublic class FreemarkerConfig {    private static Logger log = LoggerFactory.getLogger(FreemarkerConfig.class);    @Bean    public FreeMarkerConfigurer freeMarkerConfigurer(@Value("${auto_import}") String autoImport, @Value("${auto_include}") String autoInclude) {        FreeMarkerConfigurer config = new FreeMarkerConfigurer();        writerProperties(config);        Configuration configuration = null;        try {            configuration = config.createConfiguration();        } catch (IOException e) {            e.printStackTrace();        } catch (TemplateException e) {            e.printStackTrace();        }        setAutoImport(autoImport,configuration);        setAutoInclude(autoInclude,configuration);        config.setConfiguration(configuration);        return config;    }    @Autowired    private FreeMarkerProperties properties;

    private void writerProperties(FreeMarkerConfigurer config) {        config.setTemplateLoaderPaths(this.properties.getTemplateLoaderPath());        config.setPreferFileSystemAccess(this.properties.isPreferFileSystemAccess());        config.setDefaultEncoding(this.properties.getCharsetName());        Properties settings = new Properties();        settings.putAll(this.properties.getSettings());        config.setFreemarkerSettings(settings);    }    private void setAutoImport(String autoImport,Configuration configuration) {        if("_".equals(autoImport.trim())) {            return;        }        String[] imports = autoImport.split(";");        Map<String,String> importMap = new HashMap<String,String>(imports.length);        for (String s : imports) {            String[] keyValue = s.split("as");            if (keyValue.length != 2) {                log.error("freemarker配置auto_import格式不正确 ");                throw new RuntimeException("freemarker配置auto_import格式不正确");            }            importMap.put(keyValue[1].trim(),keyValue[0].trim());        }        configuration.setAutoImports(importMap);    }    private void setAutoInclude(final String autoInclude,Configuration configuration) {        if ("_".equals(autoInclude.trim())) {            return;        }        String[] includes = autoInclude.split(";");        for (String s : includes) {            System.out.println(s);        }        List list = new ArrayList<String>(Arrays.asList(includes));        configuration.setAutoIncludes(list);    }}
