本文实例为大家分享了spring，spring mvc，mongodb实现登录注册 的具体代码，供大家参考，具体内容如下

model层：
我要评论
package com.model;
import org.springframework.data.annotation.id;
import org.springframework.data.document.mongodb.mapping.document;
@document(collection = "p3")
public class user {
@id
string name;
string password;
public string getname() {
return name;
}
public void setname(string name) {
this.name = name;
}
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
}
userdao:
package com.userdao;
import com.model.user;
public interface userdao {
public void insert(user user);
public boolean find(string name,string password);
public void save(user user);
}
userdaoimpl:
package com.userdaoimpl;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.data.document.mongodb.mongotemplate;
import org.springframework.data.document.mongodb.query.criteria;
import org.springframework.data.document.mongodb.query.query;
import com.model.user;
import com.userdao.userdao;
public class userdaoimpl implements userdao{
@autowired
mongotemplate mongotemplate;
@override
public void insert(user user) {
getmongotemplate().insert(user);
}
@override
public boolean find(string name, string password) {
criteria criteria=criteria.where("name").is(name).and("password").in(password);
user user = getmongotemplate().findone(new query(criteria), user.class);
if (user==null) {
return false;
}
return true;
}
@override
public void save(user user) {
getmongotemplate().save(user);
}
public mongotemplate getmongotemplate() {
return mongotemplate;
}
public void setmongotemplate(mongotemplate mongotemplate) {
this.mongotemplate = mongotemplate;
}
}
logincontroller:
package com.controller;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.controller;
import org.springframework.ui.model;
import org.springframework.web.bind.annotation.requestmapping;
import com.userdaoimpl.userdaoimpl;
@controller
public class logincontroller {
@autowired
userdaoimpl userdaoimpl;
@requestmapping("/login")
public string login(string name,string password,model model) {
boolean rs = userdaoimpl.find(name, password);
if (rs==true) {
return "index";
}
return "erro";
}
public userdaoimpl getuserdaoimpl() {
return userdaoimpl;
}
public void setuserdaoimpl(userdaoimpl userdaoimpl) {
this.userdaoimpl = userdaoimpl;
}
}
registercontroller:
package com.controller;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.controller;
import org.springframework.ui.model;
import org.springframework.web.bind.annotation.requestmapping;

@requestmapping("/register")
public string register(string name,string password,model model) {
user user = new user();
user.setname(name);
user.setpassword(password);
userdaoimpl.save(user);
return "login";
}
public userdaoimpl getuserdaoimpl() {
return userdaoimpl;
}
public void setuserdaoimpl(userdaoimpl userdaoimpl) {
this.userdaoimpl = userdaoimpl;
}
}
