【问题描述】：
我目前正在开发一个 Spring MVC 应用程序。我已经配置了一个 JDBC TransactionManager，并且我正在使用 AOP XML 进行声明性事务管理。但是，即使我将该方法配置为在 read-only=true 上运行，它仍然会提交交易。
数据库：Oracle 10g
我的数据库配置.xml

我的控制器
package com.service;
import java.util.List;
import com.mybatis.dao.EmployeeMapperInterface;
import com.spring.model.Employee;
public class EmployeeService implements EmployeeBaseService{
EmployeeMapperInterface employeeMapper;
public EmployeeMapperInterface getEmployeeMapper() {
return employeeMapper;
}
public void setEmployeeMapper(EmployeeMapperInterface employeeMapper) {
this.employeeMapper = employeeMapper;
}
@Override
public Employee getEmployeeById(long empId){
//retrieve from database
List empList = employeeMapper.getEmployeeWithId(empId);
if(empList != null && empList.size()>0){
return (Employee) empList.get(0);
}
return null;
}
@Override
public long saveEmployee(Employee employee){
long empId = 0l;
if(employee.getEmpId()==0){
empId = new Long( employeeMapper.insertEmployee(employee));
}else{
employeeMapper.updateEmployee(employee);
empId = employee.getEmpId();
}
try {
System.out.println("gonna sleep");
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
return empId;
}
如何防止自动提交？我还注意到，即使我不放任何事务管理代码，代码仍然会提交。请注意，事务建议是在我为 RuntimeException 放置 no-rollback-for 然后执行 1/0 时调用的，如果我放置与 rollback-for 相同的内容，它会正确提交数据并回滚。 我还通过将线程置于睡眠状态来尝试查询超时，即使这样也不起作用，但我认为超时可能是针对实际查询的，所以没关系。 提前致谢！
