Mybatis Plus 相关

主动调用雪花算法生成Id

IdentifierGenerator identifierGenerator = new DefaultIdentifierGenerator();
String id = identifierGenerator.nextId(null).toString();

字段可空赋值注解

@TableField(strategy=FieldStrategy.IGNORED)

乐观锁和分页

@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor(){
    // 分页
    interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
    // 乐观锁
    interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
    return interceptor;
}
