dozer 简单用法

maven添加必要的库：

         <!-- https://mvnrepository.com/artifact/net.sf.dozer/dozer -->
         <dependency>
             <groupId>net.sf.dozer</groupId>
             <artifactId>dozer</artifactId>
             <version>5.5.1</version>
         </dependency>
         <!-- https://mvnrepository.com/artifact/net.sf.dozer/dozer-spring -->
         <dependency>
             <groupId>net.sf.dozer</groupId>
             <artifactId>dozer-spring</artifactId>
             <version>5.5.1</version>
         </dependency>

spring添加bean：

     <bean id="mapper" class="org.dozer.spring.DozerBeanMapperFactoryBean">
         <property name="mappingFiles">
             <list>
                 <!--<value>classpath*:dozer/dozer-mapping.xml</value>-->
             </list>
         </property>
     </bean>

然后就可以在Java必要的地方注入mapper，例如：

     @Autowired
     private Mapper mapper;

mapper的用法：

     @Override
     public UserDto getUser(long id) {
         List<UserEnty> userEnties = getSession()
                 .createQuery("from " + UserEnty.class.getSimpleName() + " where id=:id", UserEnty.class)
                 .setParameter("id", id)
                 .list();
         if (userEnties.size() > 0){
             return mapper.map(userEnties.get(0), UserDto.class);
         }
         return null;
     }
