Data fetching from database on each hit not from the cache - spring-mvc

Question

This is the Application.java class
#Configuration
#SpringBootApplication
//#EnableGlobalMethodSecurity(prePostEnabled=true)
#EnableTransactionManagement
#EnableCaching
#EnableJpaRepositories(basePackages="om.gov.moh.irs.dao.repos",repositoryImplementationPostfix="CustomImpl")
public class Application extends SpringBootServletInitializer {
#Autowired
Environment env;
#Bean
#ConfigurationProperties("spring.datasource")
public ComboPooledDataSource dataSource() {
return new ComboPooledDataSource();
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Bean
public ResourceBundleMessageSource messageSource() {
ResourceBundleMessageSource source = new ResourceBundleMessageSource();
source.setBasenames("messages"); // name of the resource bundle
source.setUseCodeAsDefaultMessage(true);
return source;
}
#Bean
MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize(env.getProperty("multipart.maxFileSize"));
factory.setMaxRequestSize(env.getProperty("multipart.maxRequestSize"));
return factory.createMultipartConfig();
}
}
This is the dto class which Im trying to cache.
public class PaginationDto implements Serializable {
private static final long serialVersionUID = 1L;
public Integer totalRecords;
public List<?> paginatedList;
//constructor and getter setter here
}
Controller class
#RequestMapping(value="categories", method=RequestMethod.POST, produces = { "application/json" })
public #ResponseBody ResultDecorator searchCategories(#RequestBody CategoryDto categoryDto) int pageSize, #RequestParam("sort") String sortOrder) throws BusinessException{
return handler.resolveResult(categoryService.searchCategory(categoryDto), OperationEnum.SEARCH);
}
Service class where #cacheable is defined.
#Override
#Cacheable("category")
public PaginationDto searchCategory(CategoryDto categoryDto) throws CategoryException {
System.out.println("#######category");
PaginationDto paginationDtoResponse = null;
paginationDtoResponse = categoryRepoCustom.fetchCategories(categoryDto);
return paginationDtoResponse;
}
Defined ehcache.xml file
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.ehcache.org/ehcache.xsd"
updateCheck="true" monitoring="autodetect" dynamicConfig="true">
<cache name="category"
maxElementsInMemory="100" eternal="false"
overflowToDisk="false"
timeToLiveSeconds="30000" timeToIdleSeconds="0"
memoryStoreEvictionPolicy="LFU" transactionalMode="off">
</cache>
</ehcache>
On hitting this http://localhost:9190/isa/categories each time console log is printing, which means data is not fetching from the cache.
