thymeleaf全局變量定義

1、 重寫configureViewResolvers方法

@Component
public class WebMvcConfigurerAdapter implements WebMvcConfigurer {

    @Resource(name="thymeleafViewResolver")
    private ThymeleafViewResolver thymeleafViewResolver;

    @Value("${spring.env}")
    private String version = "DEV";

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        if (thymeleafViewResolver != null) {
            Map<String, Object> vars = new HashMap<>(1);
            vars.put("version", version);
            thymeleafViewResolver.setStaticVariables(vars);
        }
        WebMvcConfigurer.super.configureViewResolvers(registry);
    }
}

　　2、html中應用

<div class="environmentclass" th:data-value="${version}">
