MyBatis-Plus 指定字段的查询和排除

单个字段查询

testService.list(Wrappers.<Test>lambdaQuery().select(Test::getId));

多个字段查询

testService.list(Wrappers.<Test>lambdaQuery().select(Test::getId, Test::getAge));

单个字段排除

// 对应实体类字段testService.list(Wrappers.<Test>lambdaQuery().select(Test.class, i -> !"rName".equals(i.getProperty())));// 对应数据库字段testService.list(Wrappers.<Test>lambdaQuery().select(Test.class, i -> !"r_name".equals(i.getColumn())));

多个字段排除

// 对应实体类字段testService.list(Wrappers.<Test>lambdaQuery().select(Test.class, i -> !"rName".equals(i.getProperty()) && !"age".equals(i.getProperty())));// 对应数据库字段testService.list(Wrappers.<Test>lambdaQuery().select(Test.class, i -> !"r_name".equals(i.getColumn()) && !"age".equals(i.getColumn())));

实体类使用注解排除

@TableField(select = false)private String rName;
