前要
項目設(shè)計–宿舍管理系統(tǒng)
項目建立

配置目錄結(jié)構(gòu)
新加一個handler包，用于像mybatis自動填充的處理配置
config配置
mybatis-plus
具體配置mybaits-plus配置
注解
// 配置文件
@Configuration
// 開啟事務(wù)管理
@EnableTransactionManagement
// mapper掃描
@MapperScan("com.yu.mapper")
插件bean
這里先只配置分頁插件
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
//分頁插件
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return interceptor;
}
自動填充bean
@Bean
public GlobalConfig globalConfig() {
GlobalConfig globalConfig = new GlobalConfig();
globalConfig.setMetaObjectHandler(new MyMetaObjectHandler());
return globalConfig;
}
這里有2種寫法，注釋掉的是低版本的。高版本從3.3.0開始可以使用。不過3.3.0不要使用。有bug。
@Component
public class MyMetaObjectHandler implements MetaObjectHandler {
/**
* 新增填充創(chuàng)建時間
*
* @param metaObject
*/
@Override
public void insertFill(MetaObject metaObject) {
// this.strictInsertFill(metaObject, "createTime", LocalDateTime::now, LocalDateTime.class);
// this.strictUpdateFill(metaObject, "updateTime", LocalDateTime::now, LocalDateTime.class);
this.fillStrategy(metaObject,"createTime",LocalDateTime.now());
this.fillStrategy(metaObject,"updateTime",LocalDateTime.now());
}
/**

@Override
public void updateFill(MetaObject metaObject) {
// this.strictUpdateFill(metaObject, "updateTime", LocalDateTime::now, LocalDateTime.class);
this.fillStrategy(metaObject,"updateTime",LocalDateTime.now());
}
}

生成實體、mapper和service
