Deal all Recently started learning Jasper Report, I have some doubts about data filling. Question 1 Map<String, Object> parameter = new HashMap<>();parameter.put("my_title", "Hi, I am title");parameter.put("myBean", new MyBean());JasperPrint jasperPrint = JasperFillManager.fillReport(jasperDesign, parameter, new JREmptyDataSource()); about this code , I created parameters named "my_title" and class = java.lang.String with Jaspersoft Studio ps: <textFieldExpression><![CDATA[$P{my_title}]]></textFieldExpression> If I want to use javebean like jackson such as <textFieldExpression><![CDATA[$P{myBean.name}]]></textFieldExpression> What should I do ?
