我删除了 .jrxml 中的 uuid 部分。 uuid 属性导致另一个异常。
users_sex字段类型为smallint mysql。 iReport 自动创建类型为 java.lang.Integer 的 .jrxml 文件。
JRUser1.jrxml 预览:
我进行了搜索，但找不到任何解决方案。
最佳答案
当您具有相同的lib 2版本时会发生此问题
或者您不关闭流生成器文件.pdf
对此的调查解决方案
- 运行maven
- 依赖:树
- 分析您的重复依赖项
- 删除较旧的依赖项
- 看到你的方法generatePdfReport许多流没有关闭，你需要关闭所有打开的流
关于java - net.sf.jasperreports.engine.util.JRResourcesUtil.findClassLoaderResource(Ljava/lang/String;Ljava/lang/ClassLoader;)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39049187/
