报错内容：(前端页面部署后黄框报错内容如下，后台无明显报错)

Error occurred during deployment: : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'methodValidationPostProcessor' defined in class path resource [org/springframework/boot/autoconfigure/validation/ValidationAutoConfiguration.class]: Unsatisfied dependency expressed through method 'methodValidationPostProcessor' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'shirFilter' defined in class path resource [com/javaweb/system/config/ShiroConfig.class]: Unsatisfied dependency expressed through method 'shirFilter' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityManager' defined in class path resource [com/javaweb/system/config/ShiroConfig.clas .... msg.seeServerLog

主要问题：No qualifying bean of type 'org.springframework.jdbc.datasource.DataSourceTransactionManager' available: expected at least 1 bean which qualifies as autowire candidate.

根因：springboot如果没有显式配置数据源事务类型会启动自动加载机制，如果没有扫描到jta相关的包，就默认用DataSourceTransactionManager（这个是你们应用需要的），但是由于我们V10本身带有jta的包，导致springboot误设置为Jta事务管理器，导致异常

解决办法：

解决一：将附件apusic-web.xml放进应用包WEB-INF目录下

解决二：禁止springboot扫描jta的包 

@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.transaction.jta.JtaAutoConfiguration.class}) 排除 JtaAutoConfiguration 自动转配

解决三：显式设置事务管理器为DataSourceTransactionManager

@Configuration(
proxyBeanMethods = false)
@AutoConfigureOrder(0)
@EnableConfigurationProperties({DataSourceProperties.class{color}})
public class DataSourceTransactionManagerConfiguration {
public DataSourceTransactionManagerConfiguration() {
}

@Configuration(
proxyBeanMethods = false )
static class JdbcTransactionManagerConfiguration {
JdbcTransactionManagerConfiguration() {
}

@Bean DataSourceTransactionManager transactionManager(Environment environment, DataSource dataSource, ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers) {
DataSourceTransactionManager transactionManager = this.createTransactionManager(environment, dataSource); transactionManagerCustomizers.ifAvailable((customizers) -> {
customizers.customize(transactionManager); }); return transactionManager; }

private DataSourceTransactionManager createTransactionManager(Environment environment, DataSource dataSource) {
return environment.getProperty("spring.dao.exceptiontranslation.enabled", Boolean.class, Boolean.TRUE) ? new JdbcTransactionManager(dataSource) : new DataSourceTransactionManager(dataSource); }
}
}
