好吧，采用老式的方法… Java中的Servlets标准定义了带有参数的Map（哈希，字典）所在的Request对象，因此您可以通过以下方式访问它们：
public ModelAndView searchAssets(HttpRequest request) { StringBuilder builder = new StringBuilder(); for (String param : request.getParameterNames()) { value = request.getParameter(param); builder.append(param); builder.append("="); // or LIKE builder.append("'" + value "'"); builder.append(" AND "); } // deleting the last " AND " builder.delete(builder.length-5, builder.length); // In the entity create a method that executes a query with the string // If the parameter names are column names then you'd have to use a nativeQuery // You'd have to look it up in JPA List<Asset> list = Asset.search(builder.toString()); // put the list in the ModelAndView}
