公司旧的项目用play,新的项目改用springboot,前端同学问我,新的项目怎么拿baseUrl? 其实springboot+thymeleaf是可以做到的,我就贴个代码记录一下吧 后端代码如下:
|
1 2 3 4 5 6 7 8 9 |
@Resource private void configureThymeleafStaticVars(ThymeleafViewResolver viewResolver) { if(viewResolver != null) { Map<String, Object> vars = Maps.newHashMap(); vars.put("picUrl", env.getProperty("picUrl")); vars.put("baseUrl", env.getProperty("baseUrl")); viewResolver.setStaticVariables(vars); } } |
只要放在spring能扫描到的地方就可以了. 不过这里有个问题,一般来说,这些地址都是通过properties文件,或者yml文件,分环境配置的,要拿配置文件的值,我第一时间就想用@value,但是由于加载顺序的关系,@value加载在后面,所以这里就不能用@value了,用environment
|

@Resource private Environment env; |
然后到前端的代码: 把这段代码放到header.html,统一加载就行了

<script th:inline="javascript"> const baseUrl = '[(${baseUrl})]'; const picUrl = '[(${picUrl})]'; </script> |

可以看到springboot默认加载资源的路径是在calsspath下，这样jar打包的web项目资源文件只能放在jar内。这样修改和维护起来非常不方便。 参考官方文档，static资源也可以放在jar包外部，只要在配置文件中增加static-locations: 就可以直接在配置文件中覆盖默认的静态资源路径的配置信息 application.yml增加配置
