我有一个 Spring Batch 作业开始抛出这个奇怪的异常。

我希望我有比这个堆栈跟踪更多的信息，我可能会，但我只是不知道要提供什么。

环顾四周，我只发现另一个人有这个特殊错误，但截至 2013 年 8 月没有回复。spring.io 论坛

有人有什么建议吗？谢谢/w

这似乎是 Spring 3.2.0 和其他版本中的错误。请参阅第565 行的 org.springframework.util.ReflectionUtils.doWithFields(Class,FieldCallback,FieldFilter) 的源代码。这一行的注释表明代码应该跳过静态和/或最终字段，但是没有代码来实际实现这个测试。当然，抛出的异常是尝试修改静态 final 字段的预期结果（可以通过反射修改非静态 final 字段，但静态 final 被视为编译时常量，因此不允许修改）。

Jules 提到的问题已修复。只需升级到 Spring Batch 版本 3.0.2.RELEASE 或更高版本。

如果升级到 Spring Batch Core 3.0.2 很困难（出于任何原因），并且如果您通过 Maven 使用 jacoco 集成，则解决方案可能是在 jacoco 集成中排除 Spring 类：

<pluginManagement>
    <plugins>
        <!-- Avoid BATCH-2157 until Spring Batch Core 3.0.2 -->
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>...</version>
            <configuration>
                <excludes>
                    <exclude>**/springframework/**</exclude>
                </excludes>
            </configuration>
        </plugin>
        [...]
    </plugins>
    [...]
</pluginManagement>

Maven 测试通过了；但是对代码覆盖率的影响是不合格的（这将是最小的）。
