在开发时经常需要调整JS，但是调整后由于页面缓存的原因，看不到实时效果。
开发环境：springboot+thymeleaf
1.配置文件多模式
2.获得当前的激活的模式和随机数
import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.PropertySource;import org.springframework.core.env.Environment;import org.springframework.stereotype.Component;/** * ?* 类描述： 项目主配置文件 * */@Component(value = "app")@ConfigurationProperties(prefix = "app")@PropertySource("classpath:/config/app.properties")public class PropertiesApp { ?@Autowired ?private Environment env; ?private String staticURL; ?private String publicURL; ?private String appURL; ?public final String getStaticURL() { ???return staticURL; ?} ?public final void setStaticURL(String staticURL) { ???this.staticURL = staticURL; ?} ?public final String getPublicURL() { ???return publicURL; ?} ?public final void setPublicURL(String publicURL) { ???this.publicURL = publicURL; ?} ?public final String getAppURL() { ???return appURL; ?} ?public final void setAppURL(String appURL) { ???this.appURL = appURL; ?} ?/** ??* 获得：随机数，用作禁用页面缓存 ??* ??* @return the Rint ??*/ ?public final long getRnd() { ???return System.currentTimeMillis(); ?} ?/** ??* 获得激活的配置文件属性 ??* ???* @return ??*/ ?public String getActive() { ???return env.getProperty("spring.profiles.active"); ?}}3.在页面中判断模式和随机数
<div th:fragment="js-index"> ???<th:block th:switch="${@app.getActive()}"> ???????<script th:case="‘prod‘" type="text/javascript" th:src="(${@app.getAppURL()})+‘js/index.js‘"></script> ???????<script th:case="‘dev‘" type="text/javascript" th:src="(${@app.getAppURL()})+‘js/index.js?rnd=‘+(${@app.getRnd()})"></script> ???</th:block></div>${@app.getActive()} 获得当前的激活模式
${@app.getRnd()} 获得随机数
生成的HTML：
这样每次加载的JS都是最新的，记住对业务JS实施，不要对公共的JS去做。
