Question

我正在使用spring批处理，我已经通过单击按钮（spring MVC）配置了我的作业。有关我的工作的所有信息都在数据库中的BATCH_JOB_EXECUTION。

我想要这个场景：

- 当我加载页面时，该表包含数据库中存在的所有记录

- 当我点击按钮执行我的工作时，数据库中添加的最后一条记录会添加到我表格的前端。

这就是我所做的但仍然无法正常工作！

以下是BATCH_JOB_EXECUTION.java文件的内容：

public class BATCH_JOB_EXECUTION {

private int JOB_EXECUTION_ID ;
private int VERSION;
private int JOB_INSTANCE_ID;
private Time CREATE_TIME ;
private Time START_TIME;
private Time END_TIME;
private String STATUS;
private String EXIT_CODE;
private String EXIT_MESSAGE;
private Time LAST_UPDATED;
public BATCH_JOB_EXECUTION(){

}
public int getJOB_EXECUTION_ID() {
    return JOB_EXECUTION_ID;
}
public void setJOB_EXECUTION_ID(int jOB_EXECUTION_ID) {
    JOB_EXECUTION_ID = jOB_EXECUTION_ID;
}
public int getVERSION() {
    return VERSION;
}
public void setVERSION(int vERSION) {
    VERSION = vERSION;
}
public int getJOB_INSTANCE_ID() {
    return JOB_INSTANCE_ID;
}
public void setJOB_INSTANCE_ID(int jOB_INSTANCE_ID) {
    JOB_INSTANCE_ID = jOB_INSTANCE_ID;
}
public Time getCREATE_TIME() {
    return CREATE_TIME;
}
public void setCREATE_TIME(Time cREATE_TIME) {
    CREATE_TIME = cREATE_TIME;
}
public Time getSTART_TIME() {
    return START_TIME;
}
public void setSTART_TIME(Time sTART_TIME) {
    START_TIME = sTART_TIME;
}
public Time getEND_TIME() {
    return END_TIME;
}
public void setEND_TIME(Time eND_TIME) {
    END_TIME = eND_TIME;
}
public String getSTATUS() {
    return STATUS;
}
public void setSTATUS(String sTATUS) {
    STATUS = sTATUS;
}
public String getEXIT_CODE() {
    return EXIT_CODE;
}
public void setEXIT_CODE(String eXIT_CODE) {
    EXIT_CODE = eXIT_CODE;
}
public String getEXIT_MESSAGE() {
    return EXIT_MESSAGE;
}
public void setEXIT_MESSAGE(String eXIT_MESSAGE) {
    EXIT_MESSAGE = eXIT_MESSAGE;
}
public Time getLAST_UPDATED() {
    return LAST_UPDATED;
}
public void setLAST_UPDATED(Time lAST_UPDATED) {
    LAST_UPDATED = lAST_UPDATED;
}
}

这是我的观点：

 <div>
        <table id="contactTableResponse" class="table tr">
            <thead>
                <tr>
                    <th>JOB_INSTANCE_ID</th>
                    <th>START_TIME</th>
                    <th>END_TIME</th>
                    <th>EXIT_CODE</th>

                </tr>
            </thead>
            <tfoot>
                <tr>
                    <th scope="row">Spring-Ajax</th>
                    <td colspan="4">JQuery Ajax</td>
                </tr>
            </tfoot>
            <tbody>
                <c:forEach items="${jobs}" var="BATCH_JOB_EXECUTION">
                        <tr>

                        <td>${BATCH_JOB_EXECUTION.JOB_INSTANCE_ID}</td>
                        <td>${BATCH_JOB_EXECUTION.START_TIME}</td>
                        <td>${BATCH_JOB_EXECUTION.END_TIME}</td>
                        <td>${BATCH_JOB_EXECUTION.EXIT_CODE}</td>
                    </tr>
                </c:forEach>
            </tbody>
        </table>
    </div>

ajax电话：

    $('#JobBtn').click( function() {
  $('#JobBtn').click( function() {
    alert('in submit function');
    $.ajax({
        type: 'GET',
        url: 'load',

        success : function(response) {  
            alert(response);   
           },  
           error : function(e) {  
            alert('Error: ' + e);   
           }  
    });
});

更新

这是我的控制者：

 public class AjacController {

@Inject
@Named(value = "dataSource")
 private DataSource dataSource1;

 @RequestMapping(value="/load" )
 public ModelAndView connect(){


    ModelAndView model = new ModelAndView("");
    BATCH_JOB_EXECUTION batch=null;
     List<BATCH_JOB_EXECUTION> list =null;
ResultSet resultSet = null;
PreparedStatement preparedStatement = null;
Connection connection = null;
String select= "select JOB_INSTANCE_ID, START_TIME,END_TIME,EXIT_CODE  from BATCH_JOB_EXECUTION";

 try {
    connection = dataSource1.getConnection();
    preparedStatement = connection.prepareStatement(select);
    resultSet = preparedStatement.executeQuery();
    while(resultSet.next()){


   batch.setJOB_EXECUTION_ID(resultSet.getInt("JOB_INSTANCE_ID")) ;
   batch.setSTART_TIME(resultSet.getTime("START_TIME")) ;
   batch.setEND_TIME(resultSet.getTime("END_TIME")) ;
   batch.setEXIT_CODE(resultSet.getString("EXIT_CODE")) ;
   list.add(batch);
   model.addObject("listJobs", list);


    }
  return model ;

}

但我的表格中没有显示数据！任何帮助将不胜感激。

如何使用带有spring Mvc的Ajax Jquery从oracle数据库中检索数据？
