我已经尝试了几乎所有我可以在网上和这个特定网站上找到的东西,但这些选项都不起作用。我正在遍历对象列表并创建一个 CSV 文件。我想打破每个对象条目,但到目前为止还没有运气。
这是我目前拥有的:
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();
}
所以这些东西都不起作用。我的输出看起来像这样:
jeff,smith,jsmith@email.com,555-123-1234 rick,smith,rsmith@email.com,123-123-1233
应该看起来像:
杰夫,史密斯,jsmith@email.com,555-123-1234
rick,smith,rsmith@email.com,123-123-1233
