我已经尝试过在网上和这个特定网站上找到的所有内容,但这些选项都没有效果。我循环遍历对象列表并创建CSV文件。我想打破每个对象条目,但到目前为止没有运气。
以下是我目前的情况:
String value = FacesContext.getCurrentInstance().
getExternalContext().getRequestParameterMap().get("cityId");
String seperator = System.getProperty("line.separator");
try {
PortletResponse response1 = (PortletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
HttpServletResponse resp = PortalUtil.getHttpServletResponse(response1);
resp.setHeader("Content-Type", "text/csv");
resp.setHeader("Content-disposition", "attachment;filename=myFile.csv");
List<Person> people = ppApi.getPeopleByCityId(Long.parseLong(value));
PrintWriter out = resp.getWriter();
for(Person pp : people) {
out.print(pp.getFirstName() + ",");
out.print(pp.getLastName() + ",");
out.print(pp.getEmail() + ",");
out.print(pp.getPhone() + "%%n");
out.print("\r\n");
out.print("\n\r");
out.print("\n");
out.print("\r");
out.print("\\r\\n");
out.print("\\n");
out.print("\\n\\r");
out.print(seperator);
out.println('\n');
out.println("%n");
out.println("%%n");
}
//Close the output stream
out.flush();
out.close();
}
catch(Exception e) {
e.printStackTrace();
}
所以这些都没有奏效。我的输出看起来像这样:
杰夫,史密斯,jsmith的@ email.com,555-123-1234 瑞克,史密斯,rsmith @ email.com,123-123-1233
应该是这样的:
杰夫,史密斯,jsmith的@ email.com,555-123-1234
瑞克,史密斯,rsmith @ email.com,123-123-1233
