数据库是可以连接上的，前台调用请求，后台如何获得前台的数据，加入到sql语句中进行查询？
新手刚开始搞这个，最简单的一个数据查询功能

简单看下jsp页面

">
Person Form


">Person List

Person Form

Name/form:label

Postcode/form:label

Address/form:label

/form:form

controller

@Controller
@RequestMapping(value = "/person")
public class PersonController {
private Logger logger = LoggerFactory.getLogger(PersonController.class);

@Autowired
private PersonDao personDao;

@RequestMapping(value = "list", method = RequestMethod.GET)
public String getAddressList(Model model) {
model.addAttribute("people", personDao.selectAll());
return "person/list";
}

@RequestMapping(value = "create", method = RequestMethod.POST)
public String create(@Valid Person person, BindingResult result) {
if (result.hasErrors()) {
logger.warn(result.getFieldErrors().toString());
return "person/form";
}
this.personDao.insert(person);
return "redirect:/person/list";
}
}

public class Person {
private Long id;
@NotEmpty
private String name;
@NotEmpty
private String postcode;
@NotEmpty
private String address;

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getPostcode() {
return postcode;
}

public void setPostcode(String postcode) {
this.postcode = postcode;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}
}
表单会提交到create这个方法，这个时候会用Person 去自动获取表单里面对应的值。
这个时候你可以使用get方法获取里面的任何属性的值，然后再把值插入到数据库，另外还有传统的request.getParameter和@requestParam等可以获取表单的值，下面的例子你可以参考
