代码背景

小公司新项目加上本人也就两个开发，很多地方用到了字典，于是在网上参考一篇数据字典翻译类，自己记录一下，方便之后项目用到使用。

@Dict注解


import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;/*** @Author: Yin XX* @Description:* @Date: Create in 11:33 2020/4/30*/@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Dict {/*** 方法描述：数据dataSource* @return 返回类型： String*/String dictDataSource();/*** 方法描述：这是返回后Put到josn中的文本key值* @return 返回类型： String*/String dictText() default "";
}

分页工具类

service层查询接口

service实现类和Mybatis的SQL语句

    @Overridepublic String selectByFieldNameAndFieldValue(String fieldName, String fieldValue) {DictionariesEntity entity = this.baseMapper.selectByFieldNameAndFieldValue(fieldName, fieldValue);if(entity ==null){return "无翻译词汇";}return entity.getFieldDetail();}==============================分割线，以下是SQL=================================================<!--通过表格字段名和字段值查询该字典信息--><select id="selectByFieldNameAndFieldValue" parameterType="java.lang.String"resultType="io.renren.modules.dictionaries.entity.DictionariesEntity">SELECT * FROM pz_dictionaries<where><if test="fieldName != null and fieldName !=''">field_name = #{fieldName}</if><if test="fieldValue != null and fieldValue !=''">and field_value = #{fieldValue}</if></where></select>

实体类

每次新增或修改数据字典时候清空当前缓存

/*** 保存* @param entity* @return*/@RequestMapping("/save")@RequiresPermissions("dictionaries:list")@CacheEvict(value="dictEhcache", allEntries=true) //清空缓存public R save(@RequestBody DictionariesEntity entity) {String errMassage = "保存失败";if(entity != null){Map<String,Object> parMap = new HashMap<>();parMap.put("field_name",entity.getFieldName());parMap.put("field_value",entity.getFieldValue());Collection<DictionariesEntity> collections = service.listByMap(parMap);if(collections.size()==0){boolean b = service.save(entity);if (b) {return R.ok();}}else {errMassage="该表'字段名'和'字段码值'已存在";}}return R.error().put("msg",errMassage);}

数据表

pz_dictionaries表字段：

字段名	类型	备注
id	varchar	uuid,唯一标识
field_name	varchar	对应表格字段名
field_value	varchar	字段值
field_detail	varchar	字段说明
field_describe	varchar	具体描述
