Spring SPRINGMVC Hibernate consolidated Java Web project __web

The main is to configure ApplicationContext and Springmvc.xml

Applicationcontext.xml includes the introduction of database properties files, component scans excluding the Controller layer's service layer and the DAO layer

Creates a DataSource bean object and its properties, properties, and the properties of the database connection.

Create sqlsession bean objects, inject data sources, configure Hibernate's attribute SQL formatting, create tables, and dialects;

Creates a transaction-managed bean object, injecting the Sqlsession object,

Use the annotation method of transaction management: <tx:annotation-driven transationmanager= "Transationmanager"/>

Springmvc.xml

Component scans include controller layer exclude service layer and DAO layer

The configuration Content Negotiation Management Bean object contains the media type properties and the default content type;

"Mvc:anotation-driven"

Mvc:default-servlet-handler

and view parser prefixes and suffixes

entity classes, @Entity @Table

"Person")

Controller class @controller Service class @Service DAO class using annotation way @repository;

Class is used in

@Autowired

  Personservice;

@Autowired
Persondao;

@Resource
sessionfactory;

Automatically injects the class to be invoked;

With such annotations, the corresponding Bean objects are not configured in the configuration file;

1, the introduction of the corresponding jar package, Spring package: Spring-aop spring-aspect spring-context Spring-beans spring-core spring-orm Spring-tx spring-test Spring-web Spring-jdbc about 11

Hibernate package: Hibernate3, required under Lib: Jta javaassist slf4j commons-collections dom4j Antrl and HIBERNATE-JPA about 8

and Mysql-connect-java.

Sping-dependent packages spingsource...mchange...c3p0 springsource....commons-logging Spingsource. Aop.. Springsource...aspect. springsource.log4j.slf4j-log4j about 7

Establish package and class Com.mz.wfy.domain Person.java

ID//primary Key ID
 name,//name
idcard;//ID number phone
 number
 address 

All of the above are string type    encapsulation and toString methods       

@Id
"Id"falsetrue) "
generator""UUID")
"Generator" )

"Name" false, length = 32)

Establish the corresponding hibernate mapping file User.hbm.xml the table and entity mapping of the database; there are ID (including generator node) property section under the Class node (name table attribute) in hibernate-mapping Point (Name Colomn property)

3. Create various properties files and profiles, A jdbc.properties

Jdbc.driverclass=com.mysql.jdbc.driver; JDBC. url=jdbc:mysql://localhost:3306/sprsh?useunicode=yes&characterencoding=utf-8

Jdbc.uername=root jdbc.password=123456

B log4j.properties ..... Baidu Search can be, this later detailed study;

C Applicationcontext.xml

< contextBase-package= "Com.mz.wfy"> < context
     type = "Annotation" 
 expression ="Org.springframework.stereotype.Controller"/> </     
 Context : Component-scan>

A introduce an external property file Jdbc.properties use

<context:property-placeholder location= "Classpath:jdbc.properties"/>

b Configure connection pooling, DataSource data source bean objects

<bean id= "DataSource" class= "com.springframework.org.mchange.c3p0....>

<property name= "Driverclass" value= "${jdbc. driverclass}"/>

<property name= "Jdbcurl" value= "${jdbc. URL}"/>

<property name= "Jdbc.user" value= "${jdbc. Username}"/>
