　　说句实话，很久都没使用SSH开发项目了，但是出于各种原因，再次记录一下整合方式，纯注解零配置。

一。前期准备工作

gradle配置文件：

group 'com.bdqn.lyrk.ssh.study'version '1.0-SNAPSHOT'apply plugin: 'war'repositories {    mavenLocal()    mavenCentral()}dependencies {    // https://mvnrepository.com/artifact/org.apache.struts/struts2-core    compile group: 'org.apache.struts', name: 'struts2-core', version: '2.5.14.1'// https://mvnrepository.com/artifact/org.apache.struts/struts2-spring-plugin    compile group: 'org.apache.struts', name: 'struts2-spring-plugin', version: '2.5.14.1'// https://mvnrepository.com/artifact/org.springframework/spring-context    compile group: 'org.springframework', name: 'spring-context', version: '5.0.4.RELEASE'// https://mvnrepository.com/artifact/org.springframework/spring-web    compile group: 'org.springframework', name: 'spring-web', version: '5.0.4.RELEASE'// https://mvnrepository.com/artifact/org.hibernate/hibernate-core    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.2.12.Final'// https://mvnrepository.com/artifact/org.hibernate/hibernate-validator    compile group: 'org.hibernate', name: 'hibernate-validator', version: '5.4.1.Final'// https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api    compile group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'// https://mvnrepository.com/artifact/org.springframework/spring-orm    compile group: 'org.springframework', name: 'spring-orm', version: '5.0.4.RELEASE'    // https://mvnrepository.com/artifact/org.springframework/spring-tx    compile group: 'org.springframework', name: 'spring-tx', version: '5.0.4.RELEASE'    // https://mvnrepository.com/artifact/com.zaxxer/HikariCP    compile group: 'com.zaxxer', name: 'HikariCP', version: '2.7.4'// https://mvnrepository.com/artifact/org.apache.struts/struts2-convention-plugin    compile group: 'org.apache.struts', name: 'struts2-convention-plugin', version: '2.5.14.1'    testCompile group: 'junit', name: 'junit', version: '4.11'}

结构文件：

spring+hibernate+struts2零配置整合

注意在classpath下创建META-INF/services/javax.serlvet.ServletContainerInitializer文件，那么在文件中定义的类在servlet容器启动时会执行onStartup方法，我们可以在这里编码创建servlet,fliter,listener等，文件内容如下：

com.bdqn.lyrk.ssh.study.config.WebInitializer

二。具体的集成实现方案

1.定义 MyAnnotationConfigWebApplicationContext

package com.bdqn.lyrk.ssh.study.config;import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;/** * 自定义配置，为了在ContextLoaderListener初始化注解配置时使用 * @Author chen.nie */public class MyAnnotationConfigWebApplicationContext extends AnnotationConfigWebApplicationContext {    public MyAnnotationConfigWebApplicationContext(){        this.register(AppConfig.class);    }}

2.定义WebInitializer

package com.bdqn.lyrk.ssh.study.config;import org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter;import org.springframework.orm.hibernate5.support.OpenSessionInViewFilter;import org.springframework.web.context.ContextLoaderListener;import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;import javax.servlet.*;import javax.servlet.annotation.HandlesTypes;import javax.servlet.http.HttpServlet;import java.util.EnumSet;import java.util.Set;/** * 自定义servlet容器初始化，请参考servlet规范 */@HandlesTypes({HttpServlet.class, Filter.class})public class WebInitializer implements ServletContainerInitializer {    @Override    public void onStartup(Set<Class<?>> c, ServletContext ctx) throws ServletException {        /*            创建struts2的核心控制器         */        StrutsPrepareAndExecuteFilter strutsPrepareAndExecuteFilter = ctx.createFilter(StrutsPrepareAndExecuteFilter.class);        OpenSessionInViewFilter openSessionInViewFilter = ctx.createFilter(OpenSessionInViewFilter.class);        /*            向servlet容器中添加filter         */        ctx.addFilter("strutsPrepareAndExecuteFilter", strutsPrepareAndExecuteFilter).                addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "/*");        FilterRegistration.Dynamic dynamic = ctx.addFilter("openSessionInViewFilter", openSessionInViewFilter);        dynamic.setInitParameter("flushMode", "COMMIT");        dynamic.setInitParameter("sessionFactoryBeanName","localSessionFactoryBean");        dynamic.setInitParameter("singleSession","true");        dynamic.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "/*");        /*            添加监听器         */        ContextLoaderListener contextLoaderListener = new ContextLoaderListener();        ctx.addListener(contextLoaderListener);        ctx.setInitParameter("contextClass", "com.bdqn.lyrk.ssh.study.config.MyAnnotationConfigWebApplicationContext");    }}

3.定义AppConfig

package com.bdqn.lyrk.ssh.study.config;import com.zaxxer.hikari.HikariDataSource;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.orm.hibernate5.HibernateTemplate;import org.springframework.orm.hibernate5.HibernateTransactionManager;import org.springframework.orm.hibernate5.LocalSessionFactoryBean;import org.springframework.transaction.annotation.EnableTransactionManagement;import javax.sql.DataSource;import java.util.Properties;/** * spring基于注解配置 * * @author chen.nie * @date 2018/3/21 **/@Configuration@ComponentScan("com.bdqn")@EnableTransactionManagementpublic class AppConfig {    /**     * 定义数据源     * @return     */    @Bean    public HikariDataSource dataSource() {        HikariDataSource hikariDataSource = new HikariDataSource();        hikariDataSource.setDriverClassName("com.mysql.jdbc.Driver");        hikariDataSource.setJdbcUrl("jdbc:mysql://localhost:3306/MySchool?characterEncoding=utf-8&useSSL=false");        hikariDataSource.setUsername("root");        hikariDataSource.setPassword("root");        return hikariDataSource;    }    /**     * 定义spring创建hibernate的Session对象工厂     * @param dataSource     * @return     */    @Bean    public LocalSessionFactoryBean localSessionFactoryBean(@Autowired DataSource dataSource) {        LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();        localSessionFactoryBean.setDataSource(dataSource);        localSessionFactoryBean.setPackagesToScan("com.bdqn.lyrk.ssh.study.entity");        Properties properties = new Properties();        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");        properties.setProperty("hibernate.show_sql", "true");        localSessionFactoryBean.setHibernateProperties(properties);        return localSessionFactoryBean;    }    /**     * 定义hibernate事务管理器     * @param localSessionFactoryBean     * @return     */    @Bean    public HibernateTransactionManager transactionManager(@Autowired SessionFactory localSessionFactoryBean) {        HibernateTransactionManager hibernateTransactionManager = new HibernateTransactionManager(localSessionFactoryBean);        return hibernateTransactionManager;    }    /**     * 定义hibernateTemplate     * @param localSessionFactoryBean     * @return     */    @Bean    public HibernateTemplate hibernateTemplate(@Autowired SessionFactory localSessionFactoryBean) {        HibernateTemplate hibernateTemplate = new HibernateTemplate(localSessionFactoryBean);        return hibernateTemplate;    }}

4.定义实体类

package com.bdqn.lyrk.ssh.study.entity;import javax.persistence.*;@Table(name = "student")@Entitypublic class StudentEntity {    @GeneratedValue(strategy = GenerationType.IDENTITY)    @Id    private Integer id;    @Column(name = "stuName")    private String stuName;    @Column(name = "password")    private String password;    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getStuName() {        return stuName;    }    public void setStuName(String stuName) {        this.stuName = stuName;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }}

5.定义service

package com.bdqn.lyrk.ssh.study.service;import com.bdqn.lyrk.ssh.study.entity.StudentEntity;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.orm.hibernate5.HibernateTemplate;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;@Servicepublic class StudentService {    @Autowired    private HibernateTemplate hibernateTemplate;    @Transactional    public int save(StudentEntity studentEntity){         hibernateTemplate.save(studentEntity);         return studentEntity.getId();    }}

6.定义action 请大家留意关于struts2注解的注意事项

package com.bdqn.lyrk.ssh.study.action;import com.bdqn.lyrk.ssh.study.entity.StudentEntity;import com.bdqn.lyrk.ssh.study.service.StudentService;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;import org.apache.struts2.convention.annotation.Action;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.ParentPackage;import org.apache.struts2.convention.annotation.Result;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Scope;/** * struts2注解配置，注意： * 1.所在的包名必须以action结尾 * 2.Action要必须继承ActionSupport父类； * 3.添加struts2-convention-plugin-xxx.jar * * @author chen.nie * @date 2018/3/21 **/@Scope("prototype")@ParentPackage("struts-default")  //表示继承的父包@Namespace(value = "/") //命名空间public class IndexAction extends ActionSupport {    @Autowired    private StudentService studentService;    @Action(value = "index", results = {@Result(name = "success", location = "/index.jsp")})    public String index() {        StudentEntity studentEntity = new StudentEntity();        studentEntity.setStuName("test");        studentEntity.setPassword("123");        studentService.save(studentEntity);        ActionContext.getContext().getContextMap().put("student", studentEntity);        return com.opensymphony.xwork2.Action.SUCCESS;    }}
