MyBatis事务不回滚原因分析

<aop:config>
	<aop:pointcut id="mmethod" expression="execution(* com.jc.bus.jttsp.service.*.*(..))" />
	<aop:advisor advice-ref="txAdvice" pointcut-ref="mmethod" />
</aop:config>

  首先检查切点是不是有问题。

  @Service注解如果被SpringMVC扫描到那么Service是不存在事务属性。

   如果发现SpringMVC包的确扫描了service，那么自行处理一下，使用Spring扫描service就可以了。

package com.jc.spring.main;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.ImportResource;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import com.jc.spring.extend.SpringContextHolder;

@Configuration
@ComponentScan(basePackages = { "com.jc.spring.extend.**","com.jc.bus.*.service.**" }, excludeFilters = { @Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class) })
@ImportResource(value = { "classpath:/com/jc/spring/main/spring-transaction.xml" })
public class RootConfig {

	@Resource(name = "dataSource")
	DataSource dataSource;
	
	@Bean(name = "jdbcTemplate")
	public JdbcTemplate jdbcTemplate() {
		return new JdbcTemplate(dataSource);
	}

}
