具体怎么写 @Param 就可以了么 我貌似接受不到

{
"draw": 2,
"start": 0,
"length": 10,
"search": null,
"order": null,
"columns": null
}
返回结果是这个
提交的表单数据

draw:2
columns[0].data:id
columns[0].searchable:true
columns[0].orderable:false
columns[0].search.regex:false
columns[1].data:name
columns[1].searchable:true
columns[1].orderable:true
columns[1].search.regex:false
columns[2].data:deviceSn
columns[2].searchable:true
columns[2].orderable:true
columns[2].search.regex:false
columns[3].data:cdtu.cdtuSn
columns[3].searchable:true
columns[3].orderable:true
columns[3].search.regex:false
columns[4].data:status
columns[4].searchable:true
columns[4].orderable:true
columns[4].search.regex:false
columns[5].data:id
columns[5].searchable:true
columns[5].orderable:false
columns[5].search.regex:false
order[0].column:1
order[0].dir:asc
start:0
length:10
search.value:2
search.regex:false
