springboot 集成 shiro 导致事务无效

问题描述前两天测试一个写事务，发现这个事务出现异常不会回滚了，一直在事务上找问题，一直没有找到，结果发现是shiro的bean先于Spring事务将userService实例化了，结果导致spring事务初始化时好无法扫描到该bean，导致这个bean上没有绑定事务，导致事务无效寻找问题在哪一、在事务本身找问题通过百度发现，大家都有以下几个原因导致事务失效数据库的引擎是否是innoDB 启动类上是否加入@EnableTransactionManagement注解方法是否为public是否是因为抛出了Exception等checked异常经过排查，发现以上原因都通过了，那么应该不是写的问题。二、在运行中找问题在上面4个原因检查时，发现将已有的service 类 copy下现在有两个除了名字其他都一模一样的类，这时运行下发现，在原来的类中@Transational失效，在新copy中的类中@Transational就起效了，这个问题好莫名奇妙，什么都没改就一个有效一个无效，现在的思路就是比较下这两个类在运行时有什么不同通过log发现打出了一下信息，说是jdbc的connection 不是Spring管的而正常回归的service类则是,调用了 JtaTransactionManager 类，而且 spring是管理jdbc的connection的通过这个分析，可以知道这spring对于这两个类的处理是不一样的，应该是spring代理或者初始化的问题，翻了下log 发现service 在ProxyTransactionManagementConfiguration 配置之前就被创建了，那应该是这里的问题了，这里就要分析下service为啥提前被创建了，发现在开始启动的是shiro ，而shiro中有个realm中引用了这些服务，所以这些服务在Transaction创建扫描之前创建了引发问题原因总结导致问题的真正原因是bean创建顺序问题，解决问题方法就是，在Transaction之后创建service。ps：呵呵，但是我还是不知道咋样才能解决创建顺序问题，继续百度之,关键词shiro 导致事务不生效果然有解决方案解决方案经过百度找到了以下的解决方法，和以下解释shiro导致springboot事务不起效解决办法BeanPostProcessor加载次序及其对Bean造成的影响分析spring boot shiro 事务无效Shrio 多realms集成：No realms have been configured! One or more realms must be presentspring + shiro 配置中部分事务失效分析及解决方案(这个方案不管用)解决方法一：在realm引用的service服务上加@lazy注解，但是这个方法我测试了下并没有起效！！！解决方法二：把在 ShiroConfig里面初始化的Realm的bean和securityManager的bean方法移动到一个新建的ShiroComponent中，利用监听器中去初始化，主要配置如下，其中ShiroComponent中UserNamePassWordRealm和WeiXinRealm是我自定义的两个Realm，换成自己的就好，ShiroConfig.javaimport java.util.LinkedHashMap;import java.util.Map;import javax.servlet.DispatcherType;import javax.servlet.Filter;import org.apache.shiro.cache.ehcache.EhCacheManager;import org.apache.shiro.mgt.SecurityManager;import org.apache.shiro.spring.LifecycleBeanPostProcessor;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;import org.springframework.boot.web.servlet.FilterRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.filter.DelegatingFilterProxy;/** * 自定义继承shiro 没有使用shiro-spring-boot-web-starter 的shiro 套件 * * @author gaoxiuya * /@Configurationpublic class ShiroConfig { /* * FilterRegistrationBean * * @return / @Bean public FilterRegistrationBean filterRegistrationBean() { FilterRegistrationBean filterRegistration = new FilterRegistrationBean();
