Question

我在一个http post请求中有两个插入操作。

之类的东西

@Service
public class StudentService {

    @Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)
    public int create(final Student student) {
        // insert into table 1

        // insert into table 2 using id return from insert 1, but something BAD happen here
    }
}

所以，我在方法级别添加了@Transactional，如上所示。

为了使其有效，我添加了tx:annotation-driven

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

所以我的app-servlet.xml看起来像

<?xml version="1.0" encoding="UTF-8"?>
<beans 
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="

        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <mvc:annotation-driven />
    <mvc:resources mapping="/res/**" location="/res/" />

    <context:component-scan base-package="com.app" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="dataSource" name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://xxx:3306/AppDb" />
        <property name="username" value="username" />
        <property name="password" value="password" />
    </bean>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
</beans>

component-scan基本上会扫描所有类，包括controller，service，model，viewmodel，{{1} }等等。

如果我删除helper，则tx:annotation-driven无法正常工作。但是一旦我添加了这个@transactional，就会出现一些错误，比如

tx:annotation-driven

如何使Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.app.service.StudentService com.app.controller.HomeController.studentRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentService' defined in file [/path/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/MathSchool/WEB-INF/classes/com/app/service/StudentService.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/cglib/transform/impl/MemorySafeUndeclaredThrowableStrategy工作。

我的项目使用spring 4.1.6和spring security 3.2.7

根据此文档Migrating from Spring Security 3.x to 4.x (XML Configuration)

Spring Security 4现在需要Spring 4（我想是Spring 4.0或4.1）。方便的是，Spring Security 3.2.x适用于Spring 3.2.x和Spring 4（仅限Spring 4.0）。

我唯一做的就是将Spring 4.1降级为Spring 4.0

Spring MVC JdbcTemplate Transactional Annotation不起作用
