ajax/javascript先后台传递对象参数
在做spring MVC开发的时候,我需要在页面的JavaScript中将js对象拼接成后台spring Controller需要接收的Javabean对象。示例如下:
/** * 更新团队资源 * * @param response * @param teamResource */ @RequestMapping(value = "/updateTeamResource", method = RequestMethod.POST) public void updateTeamResource(HttpServletResponse response, @RequestBody TeamResource teamResource) { try { TeamResource updatedResource = teamResourceService.updateTeamResource(teamResource); processSuccessDataForResponse(response, updatedResource); } catch (Exception e) { processExceptionForResponse(response, e, e.getMessage()); } }
TeamResource { /** * 资源id */ private long resourceId; /** * 资源名称 */ private String resourceName; /** * 资源类型id */ private int resourceTypeId; /** * 资源配置 * * <pre> * 当为mysql资源时 ,{"host":"10.1.1.1","port":"90","user":"crm","passwd":"123","db":"wdyx","isfenku":"false"} * 为 ftp资源时 {"ip":"10.11","port":"80","user":"12","passwd":"13"} * 为hive资源时, * { * "hiveSite":{ * "hive.querylog.location":"/home/users/zhouliechun/hive_log", * "hive.default.database.uri":"hdfs://nmg01-mulan-hdfs.dmop.baidu.com:54310/app/ecom/rigelci/hive" * * }, * "hadoopSite":{ * "mapred.job.tracker":"nmg01-mulan-job.dmop.baidu.com:54311", * "dfs.client.transfer.limit.usetk":"false" * } * } * * 为drun的时候 {"drun_cluster_name":"cdc_etl2,cdc_etl3"} * * * </pre> */ private String resourceValue; /** * 团队id */ private long teamId; /** * 创建时间 */ private Date gmtCreate; /** * 最后修改时间 */ private Date gmtModify; /** * 备注 */ private String note; @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((note == null) ? 0 : note.hashCode()); result = prime * result + ((gmtCreate == null) ? 0 : gmtCreate.hashCode()); result = prime * result + ((gmtModify == null) ? 0 : gmtModify.hashCode()); result = prime * result + (int) (resourceId ^ (resourceId >>> 32)); result = prime * result + ((resourceName == null) ? 0 : resourceName.hashCode()); result = prime * result + resourceTypeId; result = prime * result + ((resourceValue == null) ? 0 : resourceValue.hashCode()); result = prime * result + (int) (teamId ^ (teamId >>> 32)); return result; } @Override public boolean equals(Object obj) { if (this == obj) { return true; } if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } TeamResource other = (TeamResource) obj; if (note == null) { if (other.note != null) { return false; } } else if (!note.equals(other.note)) { return false; } if (gmtCreate == null) { if (other.gmtCreate != null) { return false; } } else if (!gmtCreate.equals(other.gmtCreate)) { return false; } if (gmtModify == null) { if (other.gmtModify != null) { return false; } } else if (!gmtModify.equals(other.gmtModify)) { return false; } if (resourceId != other.resourceId) { return false; } if (resourceName == null) { if (other.resourceName != null) { return false; } } else if (!resourceName.equals(other.resourceName)) { return false; } if (resourceTypeId != other.resourceTypeId) { return false; } if (resourceValue == null) { if (other.resourceValue != null) { return false; } } else if (!resourceValue.equals(other.resourceValue)) { return false; } if (teamId != other.teamId) { return false; } return true; } @Override public String toString() { return "Resource [resourceId=" + resourceId + ", resourceName=" + resourceName + ", resourceTypeId=" + resourceTypeId + ", resourceValue=" + resourceValue + ", teamId=" + teamId + ", gmtCreate=" + gmtCreate + ", gmtModify=" + gmtModify + ", note=" + note + "]"; } public long getResourceId() { return resourceId; } public void setResourceId(long resourceId) { this.resourceId = resourceId; } public String getResourceName() { return resourceName; } public void setResourceName(String resourceName) { this.resourceName = resourceName; } public int getResourceTypeId() { return resourceTypeId; } public void setResourceTypeId(int resourceTypeId) { this.resourceTypeId = resourceTypeId; } public String getResourceValue() { return resourceValue; } public void setResourceValue(String resourceValue) { this.resourceValue = resourceValue; } public long getTeamId() { return teamId; } public void setTeamId(long teamId) { this.teamId = teamId; } public Date getGmtCreate() { return gmtCreate; } public void setGmtCreate(Date gmtCreate) { this.gmtCreate = gmtCreate; } public Date getGmtModify() { return gmtModify; } public void setGmtModify(Date gmtModify) { this.gmtModify = gmtModify; } public String getNote() { return note; } public void setNote(String note) { this.note = note; } }
var args = { resourceId: resourceId, resourceName: resourceName, resourceTypeId: resourceType, resourceValue: resourceValue, teamId: teamId, note: comments }; args = JSON.stringify(args);//这一步很关键 var options = { url: window.basePath + url, contentType: 'application/json',//这里也很关键,否则后台收不到 type: 'post', dataType: 'json', data: args, success: function(rs) { if (0 === rs.status) { window.showTipMessage(msg, function() { bd.m.tools.closeProgress(); // 隐藏panel bd.v.layout.whole.hide(); // 刷新Grid bd.m.grid.reloadGrid(); }); } else { window.showErrorMessage('操作失败!原因是:' + rs.statusInfo, function() { bd.m.tools.closeProgress(); }); } }, error: function(rs) { bd.m.tools.closeProgress(); } }; $.ajax(options);
