org.hibernate.LazyInitializationException: could not initialize proxy [org.alan.entity.SysUser#1] - no Session

五個解決方案

1、關閉`LazyInitialization`, 將`fetch`設成`eager`,可以在配置文件，也可注解

2、在`spring boot`的配置文件`application.properties`添加`spring.jpa.open-in-view=true`，yml同理

3、用spring 的OpenSessionInViewFilter

4、在`spring boot`的配置文件`application.properties`添加`spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true`
