1-1?pom依賴

1-2?properties(redis的基本配置以及緩存名的配置)

spring.redis.host=127.0.0.1 spring.redis.password=123456 spring.redis.port=6379 spring.redis.database=0spring.cache.cache-names=c1

1-3?Application啟動項添加

1-4 自定義KeyGenerator

@Component public class MyKeyGen implements KeyGenerator {@Overridepublic Object generate(Object o, Method method, Object... objects) {return method.getName()+":"+ Arrays.toString(objects);}

1-5 service層

@Service //@CacheConfig(cacheNames = "c1") public class BookService { // key = "#methodName" // key = "#method.name" // key = "#caches[0]" // key = "#args[0]" // @Cacheable(cacheNames = "c1",key = "#caches[0]")@Cacheable(cacheNames = "c1",key = "'myKeyGen'")public Book getUserById(Integer id){System.out.println("book>>>>>>" + id);Book book = new Book();book.setId(id);return book;}}

1-6?單元測試

@AutowiredBookService bookService;@Testpublic void contextLoads() {Book book = bookService.getUserById(1);Book book1 = bookService.getUserById(1);System.err.println("book --->>" + book);System.err.println("book1 --->>" + book1);}

2?報錯

key = "''" (需要內(nèi)嵌一下單引號 不然會報錯)
