springboot ehcache

直接上代码

一，POM

            org.springframework.boot
            spring-boot-starter-cache
        

            net.sf.ehcache
            ehcache
            2.10.8
        

二，配置xml

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

         xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
    
    
    <defaultCache
            maxElementsInMemory="10000"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            maxElementsOnDisk="10000000"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU">
        
    
 
    
    
           timeToIdleSeconds="5"
           timeToLiveSeconds="5"
           maxEntriesLocalHeap="10000"
           maxEntriesLocalDisk="10000000"
           diskExpiryThreadIntervalSeconds="120"
           overflowToDisk="false"
           memoryStoreEvictionPolicy="LRU">
    

application.yml:

spring:
  cache:
    type: ehcache
    ehcache:
      config: classpath:config/ehcache.xml

启动类：

添加 @EnableCaching

@SpringBootApplication
@EnableCaching
public class ReportApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(ReportApplication.class, args);
    }
 
}

三，创建Service / Impl

PS：必须有Service接口，不然缓存失效

Service:

public interface TestService {
 
    String testCache(String str);
}

Impl:

@Service
public class TestImpl implements TestService {
    @Cacheable(value = "testcache", key = "#str")
    @Override
    public String testCache(String str) {
        int a = new Random().nextInt();
        return a+"";
    }
}

四，调用

@RestController
@RequestMapping("api/test")
public class TestPController {
 
    @Autowired
    TestService testService;
 
 
    @ApiOperation(value = "report test")
    @RequestMapping(value = "test", method = RequestMethod.POST)
    public ApiResponse test(@RequestBody ApiRequest req) throws Exception {
        String a=testService.testCache(req.getData());
        return new ApiResponse<>().Success(a);
    }
 
}
