Question

我需要将spring-boot-starter-parent从1.4.2升级到最新版本：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.5.RELEASE</version>
    </parent>

但这将不再起作用：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-velocity</artifactId>
        </dependency>

我发现在1.4.7之后，速度包不再包含在父级中。怎么处理呢？升级依赖关系后，我是否可以暂停“速度”依赖关系？

Answer 1

Spring Boot 2.0依赖于Spring Framework 5.0。其中放弃了对Velocity的支持。因此，在Spring Boot 2中，不再支持Velocity。

Dropped support: Portlet, Velocity, JasperReports, XMLBeans, JDO, Guava.

如果您确实需要Velocity，建议：如果需要，请继续使用Spring Framework 4.3.x。

请阅读What's new Spring Framework 5.x

已删除的软件包，类和方法

Package beans.factory.access (BeanFactoryLocator mechanism).
Package jdbc.support.nativejdbc (NativeJdbcExtractor mechanism).
Package mock.staticmock removed from spring-aspects module.
No support for AnnotationDrivenStaticEntityMockingControl anymore.
Packages web.view.tiles2 and orm.hibernate3/hibernate4 dropped.
Minimum requirement: Tiles 3 and Hibernate 5 now.
Dropped support: Portlet, Velocity, JasperReports, XMLBeans, JDO, Guava.
Recommendation: Stay on Spring Framework 4.3.x for those if needed.
Many deprecated classes and methods removed across the codebase.
A few compromises made for commonly used methods in the ecosystem.

为什么spring-boot-starter-parent 1.4.7之后没有速度？
