1.片区的检验名称编号是否重复
1.1controller添加两个方法，检验片区编号和检验片区名称
作用为：调用方法判断片区编号与片区名称是否重复，并返回返回值
/**
* 检验片区编号是否重复
*/
@PostMapping( "/checkPqbhUnique")
@ResponseBody
public String checkXqbhUnique(TBxwPqZhk tBxwPqZhk){
String back = tBxwPqZhkService.checkPqbhUnique(tBxwPqZhk.getId(),tBxwPqZhk.getPqbh());
return back;
}
/**
* 校验片区名称是否重复
*/
@PostMapping("/checkPqmcUnique")
@ResponseBody
public String checkXqmcUnique(TBxwPqZhk tBxwPqZhk){
String back = tBxwPqZhkService.checkPqmcUnique(tBxwPqZhk.getId(),tBxwPqZhk.getPqmc());
return back;
}1.2添加service和mapper中方法
service：
/**
* 检验片区编号是否重复
*
* @param id 片区主键
* @param pqbh 片区编号
* @return 结果
*/
public String checkPqbhUnique(String id, String pqbh);
/**
* 检验片区编号是否重复
*
* @param id 片区主键
* @param pqmc 片区名称
* @return 结果
*/
public String checkPqmcUnique(String id, String pqmc);serviceImp：
/**
* 检验片区编号是否重复
*
* @param id 片区主键
* @param pqbh 片区编号
* @return 0表示唯一，1表示重复
*/
@Override
public String checkPqbhUnique(String id, String pqbh) {
// TODO Auto-generated method stub
if (id != null && id.length() != 0) {
}else {
id = "1";
}
Map <String , String> map = new HashMap <String , String> ();
map.put("id", id);
map.put("pqbh", pqbh);
int count = tBxwPqZhkMapper.checkPqbhUnique(map);
if (count > 0)
{
return "1";
}
return "0";
}
/**
* 检验片区名称是否重复
*
* @param id 片区主键
* @param pqmc 片区名称
* @return 0表示唯一，1表示重复
*/
@Override
public String checkPqmcUnique(String id, String pqmc) {
// TODO Auto-generated method stub
if (id != null && id.length() != 0) {
}else {
id = "1";
}
Map <String , String> map = new HashMap <String , String> ();
map.put("id", id);
map.put("pqmc", pqmc);
int count = tBxwPqZhkMapper.checkPqmcUnique(map);
if (count > 0)
{
return "1";
}
return "0";
}mapper：
/**
* 校验片区编号是否唯一
*
* @param Map id：片区编号 pqbh:片区名称
* @return 结果
*/
public int checkPqbhUnique(java.util.Map Map);
/**
* 校验片区编号是否唯一
*
* @param Map id：片区编号 pqmc:片区名称
* @return 结果
*/
public int checkPqmcUnique(java.util.Map Map);1.3添加mapper.xml文件方法
添加对应函数的连接数据库方法：
<select id="checkPqbhUnique" parameterType="java.util.Map" resultType="int">
select count(1) from t_bxw_pq_zhk where id != #{id} and pqbh=#{pqbh} and rownum <![CDATA[ <= ]]> 1
</select>
<select id="checkPqmcUnique" parameterType="java.util.Map" resultType="int">
select count(1) from t_bxw_pq_zhk where id != #{id} and pqmc=#{pqmc} and rownum <![CDATA[ <= ]]> 1
</select>1.4修改add.html中代码，加入对应代码模块
注意前面需要加入id=''pqbh'' 和id="pqmc",否则代码功能不实现！！！
<th:block th:include="include :: footer" />
<script th:inline="javascript">
var prefix = ctx + "jcxx/pq"
$("#form-pq-add").validate({
//数据校验
onkeyup: false,
rules:{
pqbh:{
minlength: 2,
maxlength: 20,
digits:true,
remote: {
url: prefix + "/checkPqbhUnique",
type: "post",
dataType: "json",
data: {
"id": function() {
return $("#id").val();
},
"pqbh": function() {
return $.common.trim($("#pqbh").val());
}
},
dataFilter: function(data, type) {
return $.validate.unique(data);
}
}
},
pqmc:{
remote: {
url: prefix + "/checkPqmcUnique",
type: "post",
dataType: "json",
data: {
"id": function() {
return $("#id").val();
},
"pqmc": function() {
return $.common.trim($("#pqmc").val());
}
},
dataFilter: function(data, type) {
return $.validate.unique(data);
}
}
}
},
messages: {
"pqbh": {
remote: "片区编号已经存在！"
},
"pqmc": {
remote: "片区名称已经存在！"
}
},
focusCleanup: true
});
function submitHandler() {
if ($.validate.form()) {
$.operate.save(prefix + "/add", $('#form-pq-add').serialize());
}
}
</script>编辑功能中的重复信息提示也一样，修改edit.html即可，与pq.html一致
1.5功能实现
2.按序排列
2.1法一：在pq.html中加入sort语句
2.2功能实现
按照默认值片区编号进行排序
2.3法二：在pq.html中加入sort语句
2.4功能实现
可以通过点击红框处进行对应的升序或降序排序
3.片区删除时，输出提示框，若存在子街道，则不能删除
3.1连接片区表和街道表
3.1.1分析二者关系，修改domain文件
一个片区可以有多个街道，一个街道属于一个片区，所以片区与街道是一对多的关系。
因此需要在街道的属性domain中加入片区属性，正常情况下加入片区属性TBxwPq最好，但是为了代码的简易及基本的功能的实现，本代码中只加入了片区id(外键，原本就有的)和片区名称(pqmc)，并生成对应的get和set方法。
3.1.2修改街道的xml文件
在原有基础上加入片区名称(pqmc)的属性，并微调sql语句，由单表查询变为多表查询
3.1.3修改街道html文件
将原来的片区id修改为片区名称即可。在添加和修改时，在片区中多几处细微的修改

</html>3.1.4新建片区service方法
在街道的添加中，必须要已知现有的全部正常的片区，然后才可以在该片区下新建街道，而由于源代码中并未有函数方法能够完成这一操作，所以需要在pq中新建一个方法 selectTBxwPqZhkAll() 通过sql语句的修改，进行显示全部片区。
service：

mapper：
mapper.xml：
3.1.5修改街道的controller中的add
3.1.6功能实现
正确显示片区名称：
回显全部片区：
