User与Role是多对多的关系。
在更新某一个用户的同时，将用户的多个角色信息绑定到Checkbox上
Controller：
@InitBinder
public void initBinder(WebDataBinder binder) throws Exception {
binder.registerCustomEditor(Set.class, new PropertyEditorSupport() {
@Override
public void setAsText(String text) {
System.out.println(text);
// Long systemInfoId = Long.valueOf(text);
// SystemInfo systemInfo =
// systemInfoService.findById(systemInfoId);
String[] roles = text.split(",");
Set<PlatformRole> platformRoles = new HashSet<>();
PlatformRole platformRole = null;
for (int i = 0; i < roles.length; i++) {
platformRole = platformRoleService.findRoleById(Integer
.parseInt(roles[i]));
platformRoles.add(platformRole);
}
System.out.println(platformRole);
setValue(platformRoles);
}
});
}
