1.前端的訪問請求
<script type="text/javascript">
$(document).ready(function(){
var saveDataAry=[];
var data1={"userName":"test","address":"gz"};
var data2={"userName":"ququ","address":"gr"};
saveDataAry.push(data1);
saveDataAry.push(data2);
$.ajax({
type:"POST",
url:"user/saveUser",
dataType:"json",
contentType:"application/json",
data:JSON.stringify(saveData),
success:function(data){
}
});
});
</script>
2.前端的訪問請求
// 方式一:
@RequestMapping(value = "/saveUser", method = {RequestMethod.POST }})
@ResponseBody
public void saveUser(@RequestBody List<User> users) {
userService.batchSave(users);
}
// 方式二:
@RequestMapping(value = "/saveUser", method = {RequestMethod.POST }})
@ResponseBody
public void saveUser(@RequestBody List<Map<Object, Object>> maps) {
userService.batchSave(users);
}
3.其他
[1].@RequestBody可以處理一下格式:
application/json
application/xml
[2].multipart/form-data的數據格式不能使用@RequestBody 處理
SpringBoot設置文件上傳大小限制--默認為1M
SpringBoot默認上傳文件大小不能超過1MB，超過之后會報以下異常：
org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.
解決方法:
請在配置文件(application.properties/application.yml)中加入如下設置即可
低版本: 1.X
spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=10MB
高版本: 2.X
spring.servlet.multipart.max-file-size=30Mb
spring.servlet.multipart.max-request-size=30Mb
