ECharts柱状图动态获取数据

前台页面代码  

<%@ include file="/config.jsp"%>  
<%@ page language="java" contentType="text/html; charset=UTF-8"  
    pageEncoding="UTF-8"%>  
  
  
  
  
  
  
  
  
  
  
  

注释代码  

当用Ajax方式请求后台数据是一定要设置async: false，否则无法获取数据

实体类代码  

/**  
 * 固定支出统计  
 *   
 */  
@Entity  
@Table(name = "dt_account_fixed")  
public class FixedExpensesAccountEntity extends BaseEntity {  
  
    /**  */  
    private static final long serialVersionUID = 1851384083686290290L;  
  
    @Id  
    @GeneratedValue  
    private Integer id;  
    private String accountUse;// 用途  
    private String accountAmt;// 金额  
    private String createId;// 创建id  
    private String createDate;// 创建日期  
    private String updateId;// 更新id  
    private String updateDate;// 更新日期  
  
    public Integer getId() {  
        return id;  
    }  
  
    public void setId(Integer id) {  
        this.id = id;  
    }  
  
    public String getAccountUse() {  
        return accountUse;  
    }  
  
    public void setAccountUse(String accountUse) {  
        this.accountUse = accountUse;  
    }  
  
    public String getAccountAmt() {  
        return accountAmt;  
    }  
  
    public void setAccountAmt(String accountAmt) {  
        this.accountAmt = accountAmt;  
    }  
  
    public String getCreateId() {  
        return createId;  
    }  
  
    public void setCreateId(String createId) {  
        this.createId = createId;  
    }  
  
    public String getCreateDate() {  
        return createDate;  
    }  
  
    public void setCreateDate(String createDate) {  
        this.createDate = createDate;  
    }  
  
    public String getUpdateId() {  
        return updateId;  
    }  
  
    public void setUpdateId(String updateId) {  
        this.updateId = updateId;  
    }  
  
    public String getUpdateDate() {  
        return updateDate;  
    }  
  
    public void setUpdateDate(String updateDate) {  
        this.updateDate = updateDate;  
    }  
  
} 

Action类代码

/**  
 *   
 * 柱状图  
 */  
@Scope("prototype")  
@Controller  
public class FixedExpensesAccountAction extends BaseAction {  
  
    /**  */  
    private static final long serialVersionUID = 1L;  
  
    private FixedExpensesAccountEntity accountEntity = getModel();  
    Map jsonMap = new HashMap();  
    List jsonList = new ArrayList();  
    @Resource(name = "fixedExpensesAccountService")  
    private FixedExpensesAccountService fixedExpensesAccountService;  
  
    public String dataXY() {  
        jsonList = fixedExpensesAccountService.selectAll();  
        return "dataXY";  
    }  
  
    public List getJsonList() {  
        return jsonList;  
    }  
  
    public void setJsonList(List jsonList) {  
        this.jsonList = jsonList;  
    }  
  
    public Map getJsonMap() {  
        return jsonMap;  
    }  
  
    public void setJsonMap(Map jsonMap) {  
        this.jsonMap = jsonMap;  
    } 

说明代码

service和dao类就不写，service和dao主要就是实现的查询
