spring-core 3.2.9 + java 8

Question

我们已经使用Spring 3.2.9将项目升级到Java8。一旦开始使用Java 8功能，Spring将不再启动（请参见下面的堆栈跟踪）。

我试图排除asm的旧用法，并包括以下依赖项：

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm</artifactId>
    <version>5.0.3</version>
</dependency>
<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-util</artifactId>
    <version>5.0.3</version>
</dependency>
<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-commons</artifactId>
    <version>5.0.3</version>
</dependency>

但是，它不能解决问题。有人知道如何解决这个问题吗？

不幸的是，我们无法升级到Spring 4，因为我们使用了一些依赖关系，这些依赖关系使升级过程非常耗时。

Answer 1

你需要升级到Spring 4.x版本。

Spring 3.2.x将仅支持针对Java 7编译的Java 8运行时。你不能使用“静态接口”，因为这是Java 8的功能，并且无法针对Java 7进行编译。

这是一些Spring 4发行说明中的相关摘录，重点是它们：

与4.0 M1一起，我们发布了Spring Framework 3.2.3，其中包含针对最近报告的问题的修复程序，同时还包含OpenJDK 8运行时支持。Spring Framework 3.2.x将支持在JDK 8运行时上针对根据JDK 7（带有-target 1.7）或更早版本编译的应用程序进行部署。

然后，根据他们在spring.framework的build.gradle文件中的注释，他们将CGLib重新打包作为其发行版的一部分，并将ASM嵌入到项目中。

// As of Spring 4.0.3, spring-core includes asm 5.0 and repackages cglib 3.1, inlining
// both into the spring-core jar. cglib 3.1 itself depends on asm 4+, and is therefore
// further transformed by the JarJar task to depend on org.springframework.asm; this
// avoids including two different copies of asm unnecessarily.

这是4.0.3发行说明中的​​另一个相关部分，显示了它们如何嵌入其中的某些库以及Spring 4.0.3中所支持的内容。

我很高兴宣布Spring Framework 4.0.3可用。这是上周Java 8发布后框架的第一个版本。它现在是使用OpenJDK 8 GA构建的，并包括最新的ASM 5.0.1（在JDK 8 GA级别上也支持字节码，取代了我们先前使用的自定义ASM 4.2分支）。
