Question

现在我在控制器中定义了以下两个连接到两个不同数据库的bean。当前场景中的两个bean 控制器从Web服务调用收到doc_id和empID_后，同时执行。我不希望这种情况发生。

当前情景：

 @RequestMapping(value="/showEmpDetails", method=RequestMethod.GET)
        public String showEmpDetails
        (
            @RequestParam(value="doc_id", defaultValue="0") String doc_id,
            @RequestParam(value="emp_id", defaultValue="1234") String empID_
        ) 
        {    String jsonString = "";
            try {
                // Bean 1 defined for an Oracle database    
                EmployeeDao empDao = (EmployeeDao) context.getBean("empDao");

                // Bean 2 defined for different Oracle database
                EmployeeDao empForValueDao = (EmployeeDao) context.getBean("empValueDao");

                List<ShowDescription> beanONE = empForValueDao.getemployeeDetails(empID_);
                List<ShowDescription> beanTWO = empDao.getCompanyShowDocument(doc_id);
                } 
              return JsonString;
        }

预期情景：

我希望首先执行beanONE，在调用getemployeeDetails方法后在控制器中返回一个值，然后传递该值 doc_id旁边第二次调用bean的时间，如下所示。以这种方式，我在getCompanyShowDocument方法中使用的SQL查询可以生成使用这个值，并得到我期待的结果。

@RequestMapping(value="/showEmpDetails", method=RequestMethod.GET)
        public String showEmpDetails
        (
            @RequestParam(value="doc_id", defaultValue="0") String doc_id,
            @RequestParam(value="emp_id", defaultValue="1234") String empID_
        ) 
        {    String jsonString = "";
            try {

                 // Bean 1 defined for different Oracle database
                EmployeeDao empForValueDao = (EmployeeDao) context.getBean("empValueDao");


                // Bean 2 defined for an Oracle database    
                EmployeeDao empDao = (EmployeeDao) context.getBean("empDao");



                List<ShowDescription> beanONE = empForValueDao.getemployeeDetails(empID_);
                List<ShowDescription> beanTWO = empDao.getCompanyShowDocument(doc_id,returnedValue);
                } 
              return JsonString;
        }

在XML中，我将bean定义如下：

 <bean id="empDao" class="abc.edg.myproj.dao.impl.EmployeeDaoImpl"> 
        <property name="dataSource"><ref bean="DB_ONE"/></property>
    </bean> 

    <bean id="empValueDao" class="abc.edg.myproj.dao.impl.EmployeeDaoImpl"> 
        <property name="dataSource"><ref bean="DB_TWO"/></property>
    </bean>

有可能实现我上面描述的内容吗？请指教。感谢

根据评论中的要求添加getemployeeeDetails方法：

public List<ShowDescription>  getemployeeDetails(String empID) throws DaoException
        {


            DataSource ds = null;
            Connection conn = null;
            PreparedStatement pstmt2 = null;
            ResultSet rs2 = null;
            List<ShowDescription> employeeValue = new ArrayList<ShowDescription>();

            try {
                ds = jdbcTemplate.getDataSource();
                conn = ds.getConnection();
                pstmt2 = conn.prepareStatement(selectValueSQL);
                pstmt2.setString(1, empID);                 

                rs2 = pstmt2.executeQuery();            
                while(rs2.next()) {             
                    ShowDescription employeeRecord = new ShowDescription(); 
                    employeeRecord.setEmployeeValue(rs2.getString("value"));
                    employeeValue.add(employeeRecord);

                    System.out.println("I am inside getemployeeDetails method to get the cvtermPropValue");
                    System.out.println(employeeRecord.getEmployeeValue()); // Prints the value 

                }
            } catch(Throwable th) {
                //some code
            } finally {
                // Closing all resources here
            }       

            return employeeValue;
        }

在另一个之前执行一个bean
