1、新建maven項目java

選中maven-aechetype-webappmysql

group Id通常爲公司域；Artifact Id至關於項目名稱；version不須要更改；Package不使用默認，手動清空web

Finishspring

項目結構如圖報錯是由於沒有加入servlet API 暫時不用管。sql

2、配置pom.xml數據庫

保存，Maven會自動聯網去下載全部須要的jar包，只寫jar的名字，不用記住，只要去Maven中央倉庫去搜索，Maven中央倉庫地址：http://search.maven.org/完成以後，多了不少jar，而且都放到了配置的本地倉庫中，之後要再使用相同版本的jar時候，就不須要聯網下載了。express

3、修改項目結構apache

由於構建的MSSH項目的結構並非一個標準的Maven結構，咱們須要手動新建幾個Source Folderjson

這是標準的maven項目結構api

src/main/java:存放java源文件

src/main/resources:存放項目配置文件，如spring.xml,hibernate.cfg.xml。。。

src/test/java:存放test的java文件

src/test/resources:存放test時候所需的配置文件

配置Source Folder的output folder

同步項目的jdk版本

設置web.xml的路徑

further configuration available若沒有出現能夠先去掉dynamic web module的勾 apply以後再打上勾就會出現此選項設置路徑爲src/main/webapp

4、編寫配置文件

web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
 3   <display-name></display-name>
 4   
 5   <!-- Spring ApplicationContext配置文件的路徑,可以使用通配符,多個路徑用,號分隔 此參數用於後面的Spring Context 
 6         Loader -->
 7   <context-param>
 8     <param-name>contextConfigLocation</param-name>
 9     <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
10   </context-param>
11   
12   <!-- spring 監聽器 -->
13   <listener>

5、使用

@Entity
@Table(name = "DAE_USER")
public class User extends ObjectEntity{
    
    private static final long serialVersionUID = 1L;
    
    private String name;
    private String password;
    private List<Role> roleList = new ArrayList<Role>();
    
    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;
    }

    // 多對多定義
    @ManyToMany(fetch = FetchType.LAZY)
    @JoinTable(name = "DAE_USER_ROLE", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = { @JoinColumn(name = "ROLE_ID") })
    public List<Role> getRoleList() {
        return roleList;
    }

    public void setRoleList(List<Role> roleList) {
        this.roleList = roleList;
    }
    
    public void addRole(Role role){
        this.roleList.add(role);

}

User

@Component

    public List<User> getAll() {
        String hql = "from User";
        return getCurrentSession().createQuery(hql).list();

}

UserDao

}

UserManager

public class UserAction extends CrudActionSupport<User> {

    private static final long serialVersionUID = 1L;
