如何在没有 xml 配置的情况下使用 JasperReportsPdfView

我想要一个控制器方法从 JasperReports jrxml 文件返回 PDF，而不使用任何 xml 配置。

我想用一个JasperReportsPdfView。这有可能吗？我知道这可以只用 Java 代码来完成，就像这个博客中一样：

但我相信用更少的代码就可以实现:-)

这里有一些示例代码not不幸的是工作。

@RequestMapping(value = "/test/pdfreport", method = RequestMethod.GET, produces = "application/pdf")
public JasperReportsPdfView getPdf() {

    // does not work like this, unfortunately
    final Person p = userService.getUserById("the id");

    final JasperReportsPdfView view = new JasperReportsPdfView();
    view.setReportDataKey("person");
    view.addStaticAttribute("person", p); // ??
    view.setUrl("report.jrxml");
    return view;
}

感谢您的指点。

Edit:这是我的工作解决方案：

@Autowired 
private ApplicationContext appContext;

@RequestMapping(value = "/test/pdfreport", method = RequestMethod.GET, produces = "application/pdf")
public ModelAndView getPdf() {
    final List<Map<String, Object>> users = userService.getUsers();

    final JasperReportsPdfView view = new JasperReportsPdfView();
    view.setReportDataKey("users");
    view.setUrl("classpath:report.jrxml");
    view.setApplicationContext(appContext);

    final Map<String, Object> params = new HashMap<>();
    params.put("users", users);

    return new ModelAndView(view, params);
}

重要的是要包括spring-context-support打包到您的项目中。

这对我有用：

@Autowired private ApplicationContext appContext;
@Autowired private DataSource dataSource;

@RequestMapping(value = "/pdf", method = RequestMethod.GET)
public ModelAndView getPdf() {
    JasperReportsPdfView view = new JasperReportsPdfView();
    view.setJdbcDataSource(dataSource);
    view.setUrl("classpath:report.jrxml");
    Map<String, Object> params = new HashMap<>();
    params.put("param1", "param1 value");
    view.setApplicationContext(appContext);
    return new ModelAndView(view, params);
}
