caijiahao / SpringMvcPlusMongo慕课网 首页 实战 路径 猿问 手记 登录 注册 11.11 Python 手记 \ 史上最全，最详idea搭建springdata+mongoDB+maven+springmvc 史上最全，最详idea搭建springdata+mongoDB+maven+springmvc 原创 2016-10-21 10:54:297759浏览2评论 作为IT届的小弟，本篇作为本人的第一篇手记，还希望各位大牛多多指点，以下均为个人学习所得，如有错误，敬请指正。本着服务IT小白的原则，该手记比较详细。由于最近使用postgre开发大型项目，发现了关系型数据库的弊端及查询效率之慢，苦心钻研之下，对nosql的mongoDB从无知到有了初步了解。 项目环境：win10+IntelliJ IDEA2016+maven3.3.9+MongoDB 3.2+JDK1.7+spring4.1.7 推荐网站（适合学习各种知识的基础）：http://www.runoob.com/ mongo安装请参考http://www.runoob.com/mongodb/mongodb-window-install.html 由于最近osChina的maven仓库挂掉，推荐大家使用阿里的镜像，速度快的飞起 maven配置：<localRepository>F:\.m2\repository</localRepository> <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> 这里不实用idea自带maven插件，改用3.3.9 图片描述 项目结构：图片描述 这里dao与mongoDao分别为mongoDB的两种查询方式： dao为JPA的查询方式（请参考springdataJPA） mongoDao使用mongoTemplate，类似于关系型数据库使用的jdbcTemplate 不罗嗦，上代码 先看配置文件 spring-context.xm为最基本的spring配置 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"

street, int num) { this.city = city; this.street = street; this.num = num; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } public String getStreet() { return street; } public void setStreet(String street) { this.street = street; } public int getNum() { return num; } public void setNum(int num) { this.num = num; } @Override public String toString() { return "Address{" + "city='" + city + '\'' + ", street='" + street + '\'' + ", num=" + num + '}'; } } /** * Created by DuLida on 2016/10/20. */ @Document(collection="person") public class Person implements Serializable { @Id private ObjectId id; private String name; private int age; private Address address; public Person() { } public Person( String name, int age, Address address) { this.name = name; this.age = age; this.address = address; } public ObjectId getId() { return id; } public void setId(ObjectId id) { this.id = id; } public String getName() { return name; } public void

setAddress(Address address) { this.address = address; } @Override public String toString() { return "Person{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + ", address=" + address + '}'; } } JPA的dao，注意这里只要继承MongoRepository不用写注解spring就能认识这是个Repository，MongoRepository提供了基本的增删改查，不用实现便可直接调用，例如testMongo的personDao.save(persons); public interface PersonDao extends MongoRepository<Person, ObjectId> { @Query(value = "{'age' : {'$gte' : ?0, '$lte' : ?1}, 'name':?2 }",fields="{ 'name' : 1, 'age' : 1}") List<Person> findByAge(int age1, int age2, String name); } mongoTemplate的dao /** * Created by DuLida on 2016/10/21. */ public interface PersonMongoDao { List<Person> findAll(); void insertPerson(Person user); void removePerson(String userName); void updatePerson(); List<Person> findForRequery(String userName); } @Repository("personMongoImpl") public class PersonMongoImpl implements PersonMongoDao { @Resource private MongoTemplate mongoTemplate; @Override public List<Person> findAll() { return mongoTemplate.findAll(Person.class,"person"); } @Override public void insertPerson(Person person) { mongoTemplate.insert(person,"person"); } @Override public void removePerson(String userName) { mongoTemplate.remove(Query.query(Criteria.where("name").is(userName)),"person"); } @Override public void updatePerson() { mongoTemplate.updateMulti(Query.query(Criteria.where("age").gt(3).lte(5)), Update.update("age",3),"person"); } @Override public List<Person> findForRequery(String userName) { return mongoTemplate.find(Query.query(Criteria.where("name").is(userName)),Person.class); } } JPA查询的测试类： /** * Created by DuLida on 2016/10/20. */ @RunWith(SpringJUnit4ClassRunner.class) //告诉junit spring配置文件 @ContextConfiguration({"classpath:spring/spring-context.xml","classpath:spring/spring-mongo.xml"}) public class PersonDaoTest { @Resource private PersonDao personDao; /*先往数据库中插入10个person*/ @Test public void testMongo() { List<Person> persons = new ArrayList<Person>(); for (int i = 0; i < 10; i++) { persons.add(new Person("name"+i,i,new Address("石家庄","裕华路",i))); } personDao.save(persons); } @Test public void findMongo() { System.out.println(personDao.findByAge(2,8,"name6")); } } mongoTemplate查询的测试类 /** * Created by DuLida on 2016/10/21. */ @RunWith(SpringJUnit4ClassRunner.class) //告诉junit spring配置文件 @ContextConfiguration({"classpath:spring/spring-context.xml","classpath:spring/spring-mongo.xml"}) public class MongoTemplateTest { @Resource private PersonMongoImpl personMongo; @Test public void testMongoTemplate() { //personMongo.insertPerson(new Person("wukong",24,new Address("石家庄","鑫达路",20))); //personMongo.removePerson("name3"); //personMongo.updatePerson(); //System.out.println(personMongo.findAll()); System.out.println(personMongo.findForRequery("wukong")); } } 注意测试前请先通过testMongo()向数据库中插入数据。 项目源码Git地址，仅供学习使用：https://github.com/dreamSmile/mongo.git

Rotating polygons, and Making Java Executable. Model View Controller (MVC) The Model is the class that contains the data and the methods needed to use the data. The View is the interface. The Controller coordinates interactions between the Model and View. DESIGN PATTERNS: Strategy design patternis used if you need to dynamically change an algorithm used by an object at run time. The pattern also allows you to eliminate code duplication. It separates behavior from super and subclasses. The Observer pattern is a software design pattern in which an object, called the subject (Publisher), maintains a list of its dependents, called observers (Subscribers), and notifies them automatically of any state changes, usually by calling one of their methods. The Factory design pattern is used when you want to define the class of an object at runtime. It also allows you to encapsulate object creation so that you can keep all object creation code in one place The Abstract Factory Design Pattern is like a factory, but everything is encapsulated. The Singleton pattern is used when you want to eliminate the option of instantiating more than one object. (Scrabble letters app) The Builder Design Pattern is used when you want to have many classes help in the creation of an object. By having different classes build the object you can then easily create many different types of objects without being forced to rewrite code. The Builder pattern provides a different way to make complex objects like you'd make using the Abstract Factory design pattern. The Prototype design pattern is used for creating new objects (instances) by cloning (copying) other objects. It allows for the adding of any subclass instance of a known super class at run time. It is used when there are numerous potential classes that you want to only use if needed at runtime. The major benefit of using the Prototype pattern is that it reduces the need for creating potentially unneeded subclasses. Java Reflection is an API and it's used to manipulate classes and everything in a class including fields, methods, constructors, private data, etc. (TestingReflection.java) The Decorator allows you to modify an object dynamically. You would use it when you want the capabilities of inheritance with subclasses, but you need to add functionality at run time. It is more flexible than inheritance. The Decorator Design Pattern simplifies code because you add functionality using many simple classes. Also, rather than rewrite old code you can extend it with new code and that is always good. (Pizza app) The Command design pattern allows you to store a list of commands for later use. With it you can store multiple commands in a class to use over and over. (ElectronicDevice app) The Adapter pattern is used when you want to translate one interface of a class into another interface. Allows 2 incompatible interfaces to work together. It allows the use of the available interface and the target interface. Any class can work together as long as the Adapter solves the issue that all classes must implement every method defined by the shared interface. (EnemyAttacker app) The Facade pattern basically says that you should simplify your methods so that much of what is done is in the background. In technical terms you should decouple the client from the sub components needed to perform an operation. (Bank app) The Bridge Pattern is used to decouple an abstraction from its implementation so that the two can vary independently. Progressively adding functionality while separating out major differences using abstract classes. (EntertainmentDevice app) In a Template Method pattern, you define a method (algorithm) in an abstract class. It contains both abstract methods and non-abstract methods. The subclasses that extend this abstract class then override those methods that don't make sense for them to use in the default way. (Sandwich app) The Iterator pattern provides you with a uniform way to access different collections of Objects. You can also write polymorphic code because you can refer to each collection of objects because they'll implement the same interface. (SongIterator app) The Composite design pattern is used to structure data into its individual parts as well as represent the inner workings of every part of a larger object. The composite pattern also allows you to treat both groups of parts in the same way as you treat the parts polymorphically. You can structure data, or represent the inner working of every part of a whole object individually. (SongComponent app) The flyweight design pattern is used to dramatically increase the speed of your code when you are using many similar objects. To reduce memory usage the flyweight design pattern shares Objects that are the same rather than creating new ones. (FlyWeightTest app) State Pattern allows an object to alter its behavior when its internal state changes. The object will appear to change its class. (ATMState) The Proxy design pattern limits access to just the methods you want made accessible in another class. It can be used for security reasons, because an Object is intensive to create, or is accessed from a remote location. You can think of it as a gate keeper that blocks access to another Object. (TestATMMachine) The Chain of Responsibility pattern has a group of objects that are expected to between them be able to solve a problem. If the first Object can't solve it, it passes the data to the next Object in the chain. (TestCalcChain) The Interpreter pattern is used to convert one representation of data into another. The context cantains the information that will be interpreted. The expression is an abstract class that defines all the methods needed to perform the different conversions. The terminal or concrete expressions provide specific conversions on different types of data. (MeasurementConversion) The Mediator design pattern is used to handle communication between related objects (Colleagues). All communication is handled by a Mediator Object and the Colleagues don't need to know anything about each other to work together. (TestStockMediator) The Memento design pattern provides a way to store previous states of an Object easily. It has 3 main classes: 1) Memento: The basic object that is stored in different states. 2) Originator: Sets and Gets values from the currently targeted Memento. Creates new Mementos and assigns current values to them. 3) Caretaker: Holds an ArrayList that contains all previous versions of the Memento. It can store and retrieve stored Mementos. (TestMemento) The Visitor design pattern allows you to add methods to classes of different types without much altering to those classes. You can make completely different methods depending on the class used with this pattern. (VisitorTest)
