1.  模糊查询

> **切记: jeecg-boot框架前端和后端只需要更改一方即可模糊查询**

1.  前端: 组件导入

//省略其他代码
    import JInput from '@/components/jeecg/JInput'
    
    export default {
        
      name: "UserList",
      mixins: [JeecgListMixin],
      components: {
        
        SysUserAgentModal,
        UserModal,
        PasswordModal,
        JInput
      },
    //省略其他代码

1.  前端: 替换输入框

<a-col :md="6" :sm="12">
      <a-form-item label="账号">
        
        <j-input placeholder="请输入账号模糊查询" v-model="queryParam.username"></j-input>
      </a-form-item>
    </a-col>

1.  后端: 字符首尾添加\*进行模糊查询

不支持模糊查询: String name = shgMessage.getName(); // 小明  
支持模糊查询: String name = “\*”+shgMessage.getName()+ “\*” ; // \*小明\*

//框架自动生成的列表分页查询方法, shgMessage对象中需要模糊查询的字段
    public Result<?> queryAppPageListArea(ShgMessage shgMessage,
    									  @RequestParam(name="pageNo", defaultValue="1") Integer pageNo,
    									  @RequestParam(name="pageSize", defaultValue="10") Integer pageSize,
    									  HttpServletRequest req,@RequestParam("area") String area) {

1.  新建子模块,子模块中接口在swagger页面不显示问题. <[传送阵][Link 1]>
2.  如果使用swagger测试接口出现拦截,需要在shiro的配置类中加上接口排除![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NqYXZhX21hdGg_size_16_color_FFFFFF_t_70]
3.  maven镜像设置setting.xml

<mirror>
            <id>nexus-aliyun</id>
            <mirrorOf>*,!jeecg,!jeecg-snapshots</mirrorOf>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    	</mirror>

3.需要安装lombok插件,不然log会报错![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NqYXZhX21hdGg_size_16_color_FFFFFF_t_70 2]  
4.jeecg-boot登录需要安装redis服务

**注意**

1.  如果要使用jeecg-boot框架的Online模式进行代码生成,需要运行前端代码.
