ireport 用html页面上 图片怎么都出不来 全是红叉的处理办法

我用的是springmvc +mybatis+ireport 

jasper-views.xml

<context:property-placeholder location="classpath:spring-views.properties" />

<bean id="htmlReport" p:reportDataKey="datasource" 
class="org.springframework.web.servlet.view.jasperreports.JasperReportsHtmlView">
<property name="url" value="${dzxxsz}"></property>
<property name="exporterParameters">
<map>
<entry
key="net.sf.jasperreports.engine.JRExporterParameter.CHARACTER_ENCODING">
<value>UTF-8</value>
</entry>
<entry
key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN">
<value>false</value>
</entry>
<entry
key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR">
<value>false</value>
</entry>

</map>
</property>
</bean>

控制层：

@RequestMapping("/getpdfReport")
    public ModelAndView doSalesReportPDF(ModelAndView modelAndView,HttpServletRequest request) 
{
    
logger.debug("Received request to download PDF report");
MockDataFactory dataprovider = new MockDataFactory();


JRDataSource categoryData  = dataprovider.getCategoriesData();
Map<String,Object> parameterMap = new HashMap<String,Object>();

List<TUser> list=this.userServiceI.getall();
List<JUser> list1=new ArrayList<JUser>();
for (TUser tUser : list) {
JUser j=new JUser();
BeanUtils.copyProperties(tUser, j);
list1.add(j);

}
JREmptyDataSource emptyData = new JREmptyDataSource();
parameterMap.put("datasource",  new JRBeanCollectionDataSource(list1));

 /*生成HTML文件 */        modelAndView = new ModelAndView("htmlReport", parameterMap); return modelAndView; } 

 
  

spring-views.properties
