71.9 Velocity

默认情况下，Spring Boot会配置一个VelocityViewResolver，如果需要的是VelocityLayoutViewResolver，你可以自己创建一个名为velocityViewResolver的bean。你也可以将VelocityProperties实例注入到自定义视图解析器以获取基本的默认设置。

以下示例使用VelocityLayoutViewResolver替换自动配置的velocity视图解析器，并自定义layoutUrl及应用所有自动配置的属性：

@Bean(name = "velocityViewResolver")
public VelocityLayoutViewResolver velocityViewResolver(VelocityProperties properties) {
    VelocityLayoutViewResolver resolver = new VelocityLayoutViewResolver();
    properties.applyToViewResolver(resolver);
    resolver.setLayoutUrl("layout/default.vm");
    return resolver;
}
