Question

我正在尝试将数据库中的用户列表导出为pdf。当我点击我的＆＃34;打印表＆＃34;按钮此异常返回。 Button正在执行generateReport（）方法。

一些细节：

iReport 5.5.0
net.sf.jasperreports 5.5.0（pom.xml）
jasperreports 3.5.3（pom.xml）
Glassfish 4.0
JDK 1.8
Netbeans 8.1

Glassfish日志文件在这里：

ListUserController在这里：

@Controller

    UserService userService;

    @Autowired
    ServletContext context;

    @RequestMapping(value = "/list-users", method = RequestMethod.GET)

        System.out.println("listusers()");

        try {
            String url = "jdbc:mysql://localhost:3306/question3?zeroDateTimeBehavior=convertToNull";

我删除了.jrxml中的uuid部分。 uuid属性导致另一个例外。

users_sex字段类型是smallint mysql。 iReport自动创建类型为java.lang.Integer的.jrxml文件。

JRUser1.jrxml预览：

我搜索了但我无法找到任何解决方案。

Answer 1

当您拥有相同的 lib 2版本

时，会发生此问题

或不要关闭流生成器文件.pdf

此调查解决方案

run maven
依赖：树
分析您的依赖项duplicante
删除更多旧的依赖
看你的方法generatePdfReport很多流未关闭，你需要关闭所有打开的流

net.sf.jasperreports.engine.util.JRResourcesUtil.findClassLoaderResource（Ljava /郎/字符串; Ljava /郎/类加载器;）
