Springboot集成cache的key生成策略

代码接上文：深度理解springboot集成redis缓存之源码解析

  @Cacheable(cacheNames = "emp",key = "#root.methodName+'['+#id+']'")
    public Employee getEmp(Integer id) {
        System.out.println("查询"+id+"号员工");
        Employee emp = employeeMapper.getEmpById(id);
        return emp;
    }
}

debug模式下运行查看key的结果

这样key的名字就换成我们自定义的了

2.自定义key生成策略

@Configuration
public class MyCacheConfig {

    @Bean("myKey")
    public KeyGenerator keyGenerator(){
       return new KeyGenerator(){

            @Override
            public Object generate(Object target, Method method, Object... params) {
                return method.getName()+"["+ Arrays.asList(params).toString()+"]";
            }
        };
    }
}

结果依然是如此
