使用IReport制作并导出PDF文件(一）----文件名默认

1. 使用IReport画出要导出的PDF模板：

注意：这三项必须设置成图中所示：

2.代码

@RequestMapping(method=RequestMethod.GET,value="/partsChangePDF/{partsChangeId}")
public ModelAndView partsChangePDF(@PathVariable("partsChangeId") int partsChangeId,ModelAndView modelAndView){
        Map<String,Object> parameterMap = new HashMap<String,Object>();
        PartsChange change = partsChangeDao.findOne(partsChangeId);
        PartsChangeFB fb = new PartsChangeFB();
<span style="white-space:pre"></span>BeanUtils.copyProperties(change, fb);
        if (change.getOldEamMaterialCode() != null) {
        fb.setOldEamId(change.getOldEamMaterialCode().getId());
        fb.setOldEamName(change.getOldEamMaterialCode().getName());
        fb.setOldEamType(change.getOldEamMaterialCode().getType());
        fb.setOldEamCode(change.getOldEamMaterialCode().getCode());
        }
<span style="white-space:pre"></span>if (change.getNewEamMaterialCode() != null) {
        fb.setNewEamId(change.getNewEamMaterialCode().getId());
        fb.setNewEamName(change.getNewEamMaterialCode().getName());
        fb.setNewEamType(change.getNewEamMaterialCode().getType());
        fb.setNewEamCode(change.getNewEamMaterialCode().getCode());
        }
        if (change.getDept() != null) {
        fb.setDeptId(change.getDept().getId());
        fb.setDeptName(change.getDept().getName());
        }
        if ("国产化".equals(change.getPartsXZ())) {
        fb.setPartsXZ("√");
        fb.setPartsXZ2("");
        } else if ("进口替用".equals(change.getPartsXZ())) {
        fb.setPartsXZ("");
        fb.setPartsXZ2("√");
        } else {
        fb.setPartsXZ("");
        fb.setPartsXZ2("");
        }
        List<PartsChangeFB> fbList = new LinkedList<PartsChangeFB>();
        fbList.add(fb);

<span style="white-space:pre"></span>JRDataSource JRdataSource = new JRBeanCollectionDataSource(fbList);
        parameterMap.put("datasource", JRdataSource);
        modelAndView = new ModelAndView("partsChangePDF", parameterMap);
        return modelAndView;

    }
