I wanted to use the @Cacheable annotation for Spring Boot 1.5, without any external cache provider. How do I set the TTL for the simple provider case?
According to this question and other resources online, I can use Guava's CacheBuilder to set the expiry by providing a CacheConfiguration.
However, it seems Guava Cache is deprecated by Spring. So without Guava, how does one set the TTL for a simple Spring cache?
you can try
Ehcache
add dependency in your pom.xml
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>3.6.2</version>
</dependency>
implement cache
@Service
public class NumberService {
// ...
@Cacheable(
value = "squareCache",
key = "#number",
condition = "#number>10")
public BigDecimal square(Long number) {
BigDecimal square = BigDecimal.valueOf(number)
.multiply(BigDecimal.valueOf(number));
log.info("square of {} is {}", number, square);
return square;
}
}
