一、将产品提供的基础敏感词excel导入到数据库，关键代码及实现如下
创新互联公司公司2013年成立，先为银州等服务建站，银州等地企业，进行企业商务咨询服务。为银州企业网站制作PC+手机+微官网三网同步一站式服务解决您的所有建站问题。
1.添加依赖
2.代码实现如下
try {
File file = new File("/Users/suyanzhu/Downloads/word.xls");
boolean exists = file.exists();
Workbook workbook = Workbook.getWorkbook(file);
Sheet sheet = workbook.getSheet(0);
for (int i = 1;i < sheet.getRows();i++){
Cell cell1 = sheet.getCell(0, i);
Cell cell2 = sheet.getCell(1, i);
Long typeId = 1L;
if (cell1.getContents().equals("敏感词类型1")){
typeId = 1L;
}else if (cell1.getContents().equals("敏感词类型2")){
typeId = 2L;
}else if (cell1.getContents().equals("敏感词类型3")){
typeId = 3L;
}else if (cell1.getContents().equals("敏感词类型4")){
typeId = 4L;
}else if (cell1.getContents().equals("敏感词类型5")){
typeId = 5L;
}
SensitiveWordParamDTO build = SensitiveWordParamDTO
.builder().addUserId(1L)
.expressionState(2)
.name(cell2.getContents())
.replaceWord("*")
.typeId(typeId)
.build();
try {
sensitiveWordProvider.save(build);
} catch (SsHoursException e) {
e.printStackTrace();
}
}
workbook.close();
} catch (IOException e) {
e.printStackTrace();
} catch (BiffException e) {
e.printStackTrace();
}
二、一对多数据显示在一行sql
SELECT
rrc.id,
cc.nickname,
cc.mobile,
rrc.update_time,
rrc.update_user_id,
apa.optionIds
FROM
表1 rrc
LEFT JOIN (
SELECT
GROUP_CONCAT(
rrco.option_id
) optionIds,
risk_customer_id
FROM
表2 rrco
GROUP BY
rrco.risk_customer_id
) apa ON apa.risk_customer_id = rrc.id
LEFT JOIN 表3 cc ON cc.id = rrc.customer_id
LEFT JOIN 表2 rrco ON rrc.id = rrco.risk_customer_id
WHERE
rrco.option_id = 3
GROUP BY
rrc.id
三、给定数字生成1到指定数字的数字列表
// 开始值
int start = 1;
// 结束值
int end = 100;
// 生成1,2,3,4,5...100
List
