Spring 创建不带@PostConstruct注释的PrimeFaces metergauge图表
我需要从spring jpa数据中检索数据到一个托管bean类，该类创建一个Spring 创建不带@PostConstruct注释的PrimeFaces metergauge图表,spring,jsf,primefaces,Spring,Jsf,Primefaces,我需要从spring jpa数据中检索数据到一个托管bean类，该类创建一个MeterGaugeChartView。当我在@PostConstruct方法中从注入的Springbean调用值时，我得到java.lang.NullPonterException。当我删除注释时，我会得到下面的错误 java.lang.NullPointerException org.primefaces.component.chart.renderer.MeterGaugeRenderer.encodeDa
