QueryWrapper<?> queryWrapper = QueryGenerator.initQueryWrapper(?, req.getParameterMap());
代码示例:
@GetMapping(value = "/list")
public Result<IPage<JeecgDemo>> list(JeecgDemo jeecgDemo, @RequestParam(name = "pageNo", defaultValue = "1") Integer pageNo,
@RequestParam(name = "pageSize", defaultValue = "10") Integer pageSize,
HttpServletRequest req) {
Result<IPage<JeecgDemo>> result = new Result<IPage<JeecgDemo>>();
//调用QueryGenerator的initQueryWrapper
QueryWrapper<JeecgDemo> queryWrapper = QueryGenerator.initQueryWrapper(jeecgDemo, req.getParameterMap());
Page<JeecgDemo> page = new Page<JeecgDemo>(pageNo, pageSize);
IPage<JeecgDemo> pageList = jeecgDemoService.page(page, queryWrapper);
result.setSuccess(true);
result.setResult(pageList);
return result;
}
查询模式 | 用法 | 说明 |
---|---|---|
模糊查询 | 支持左右模糊和全模糊 需要在查询输入框内前或后带*或是前后全部带* | |
取非查询 | 在查询输入框前面输入! 则查询该字段不等于输入值的数据(数值类型不支持此种查询,可以将数值字段定义为字符串类型的) | |
> >= < <= | 同取非查询 在输入框前面输入对应特殊字符即表示走对应规则查询 | |
in查询 | 若传入的数据带,(逗号) 则表示该查询为in查询 | |
多选字段模糊查询 | 上述4 有一个特例,若某一查询字段前后都带逗号 则会将其视为走这种查询方式 ,该查询方式是将查询条件以逗号分割再遍历数组 将每个元素作like查询 用or拼接,例如 现在name传入值 ,a,b,c, 那么结果sql就是 name like '%a%' or name like '%b%' or name like '%c%' |
功能说明: 一键生成的代码(包括:controller、service、dao、mapper、entity、vue)
1.引入排重接口,代码如下:
import { duplicateCheck } from '@/api/api'
2.找到编码必填校验规则的前端代码,代码如下:
<a-input placeholder="请输入编码" v-decorator="['code', validatorRules.code ]"/>
code: {
rules: [
{ required: true, message: '请输入编码!' },
{validator: this.validateCode}
]
},
3.找到rules里validator对应的方法在哪里,然后使用第一步中引入的排重校验接口.
以用户online表单编码为示例,其中四个必传的参数有:
{tableName:表名,fieldName:字段名,fieldVal:字段值,dataId:表的主键},
具体使用代码如下:
validateCode(rule, value, callback){
let pattern = /^[a-z|A-Z][a-z|A-Z|\d|_|-]{0,}$/;
if(!pattern.test(value)){
callback('编码必须以字母开头,可包含数字、下划线、横杠');
} else {
var params = {
tableName: "onl_cgreport_head",
fieldName: "code",
fieldVal: value,
dataId: this.model.id
};
duplicateCheck(params).then((res)=>{
if(res.success){
callback();
}else{
callback(res.message);
}
})
}
},

注意: 如果本地安装了mysql和redis,启动容器前先停掉本地服务,不然会端口冲突。
net stop redis
net stop mysql
# 1.配置host
# jeecgboot
127.0.0.1 jeecg-boot-redis
127.0.0.1 jeecg-boot-mysql
127.0.0.1 jeecg-boot-system
# 2.修改项目配置文件 application.yml
active: dev
# 3.修改application-dev.yml文件的数据库和redis链接
修改数据库连接和redis连接,将连接改成host方式
# 4.先进JAVA项目jeecg-boot根路径 maven打包
mvn clean package
# 5.构建镜像__容器组(当你改变本地代码,也可重新构建镜像)
docker-compose build
# 6.启动镜像__容器组(也可取代运行中的镜像)
docker-compose up -d
# 7.访问后台项目(注意要开启swagger)
