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;
    }
