|

|
||||
## 一、RedisConfig.java
|
||||
|
||||
```java
|
||||
package com.openclaw.config;
|
||||
|
||||
import com.fasterxml.jackson.databind.ObjectMapper;
|
||||
import com.fasterxml.jackson.databind.SerializationFeature;
|
||||
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
|
||||
import org.springframework.context.annotation.Bean;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
import org.springframework.data.redis.connection.RedisConnectionFactory;
|
||||
import org.springframework.data.redis.core.RedisTemplate;
|
||||
import org.springframework.data.redis.serializer.*;
|
||||
|
||||
@Configuration
|
||||
public class RedisConfig {
|
||||
|
||||
@Bean
|
||||
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
|
||||
RedisTemplate<String, Object> tpl = new RedisTemplate<>();
|
||||
tpl.setConnectionFactory(factory);
|
||||
|
||||
ObjectMapper om = new ObjectMapper();
|
||||
om.registerModule(new JavaTimeModule());
|
||||
om.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
|
||||
om.activateDefaultTyping(
|
||||
om.getPolymorphicTypeValidator(),
|
||||
ObjectMapper.DefaultTyping.NON_FINAL);
|
||||
|
||||
Jackson2JsonRedisSerializer<Object> json =
|
||||
new Jackson2JsonRedisSerializer<>(om, Object.class);
|
||||
|
||||
StringRedisSerializer str = new StringRedisSerializer();
|
||||
tpl.setKeySerializer(str);
|
||||
tpl.setHashKeySerializer(str);
|
||||
tpl.setValueSerializer(json);
|
||||
tpl.setHashValueSerializer(json);
|
||||
tpl.afterPropertiesSet();
|
||||
return tpl;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```yaml
|
||||
# application.yml
|
||||
spring:
|
||||
data:
|
||||
redis:
|
||||
host: localhost
|
||||
port: 6379
|
||||
database: 0
|
||||
timeout: 3000ms
|
||||
lettuce:
|
||||
pool:
|
||||
max-active: 20
|
||||
max-idle: 10
|
||||
min-idle: 2
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 二、MybatisPlusConfig.java
|
||||
|
||||
```java
|
||||
package com.openclaw.config;
|
||||
|
||||
import com.baomidou.mybatisplus.annotation.DbType;
|
||||
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
|
||||
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
|
||||
import org.springframework.context.annotation.Bean;
|
||||
import org.springframework.context.annotation.Configuration;
|
||||
|
||||
@Configuration
|
||||
public class MybatisPlusConfig {
|
||||
|
||||
@Bean
|
||||
public MybatisPlusInterceptor mybatisPlusInterceptor() {
|
||||
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
|
||||
// 分页插件
|
||||
interceptor.addInnerInterceptor(
|
||||
new PaginationInnerInterceptor(DbType.MYSQL));
|
||||
return interceptor;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 三、IdGenerator.java
|
||||
|
||||
```java
|
||||
package com.openclaw.util;
|
||||
|
||||
import org.springframework.stereotype.Component;
|
||||
import java.time.LocalDateTime;
|
||||
import java.time.format.DateTimeFormatter;
|
||||
import java.util.concurrent.atomic.AtomicInteger;
|
||||
|
||||
/**
|
||||
* 业务单号生成器（无分布式要求，单机递增序列即可）。
|
||||
* 格式示例：
|
||||
* 订单号 ORD20260316143022000001
|
||||
* 退款号 REF20260316143022000001
|
||||
* 充值号 RCH20260316143022000001
|
||||
*/
|
||||
@Component
|
||||
public class IdGenerator {
|
||||
|
||||
private static final DateTimeFormatter FMT =
|
||||
DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
|
||||
|
||||
private final AtomicInteger seq = new AtomicInteger(0);
|
||||
|
||||
private String next(String prefix) {
|
||||
int s = seq.incrementAndGet() % 1_000_000;
|
||||
return prefix + LocalDateTime.now().format(FMT) + String.format("%06d", s);
|
||||
}
|
||||
|
||||
public String generateOrderNo() { return next("ORD"); }
|
||||
public String generateRefundNo() { return next("REF"); }
|
||||
public String generateRechargeNo(){ return next("RCH"); }
|
||||
}
|
||||
```

||||
