Spring框架中XML配置事务控制的示例分析

这篇文章主要介绍Spring框架中XML配置事务控制的示例分析，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

一、基于 XML 的声明式事务控制

1.环境搭建

拷贝必要的 jar 包到工程的 lib 目录

2.创建 spring 的配置文件并导入约束

这里直接给出本次测试的全部XML配置，具体细节在后面依次介绍。

3.准备数据库表和实体类

user数据库表

create database mybase2;USE mybase2;CREATE TABLE `user` (        `id` INT(10) NOT NULL AUTO_INCREMENT COMMENT '主键',        `name` VARCHAR(20) NOT NULL DEFAULT '0',        `age` INT(10) NOT NULL DEFAULT '0',        PRIMARY KEY (`id`))COLLATE='utf8_general_ci'ENGINE=InnoDB;INSERT INTO user values(NULL,'周冬雨',21);INSERT INTO user values(NULL,'马冬梅',18);INSERT INTO user values(NULL,'马西梅',19);

User实体类

package com.gql.entity;import java.io.Serializable;/** * 类说明: *         User实体类 * @guoqianliang1998. */public class User implements Serializable {        /**         * 生成序列号         */        private static final long serialVersionUID = -4492760954899814333L;        private int id;        private String name;        private int age;                public int getId() {                return id;        }        public void setId(int id) {                this.id = id;        }        public String getName() {                return name;        }        public void setName(String name) {                this.name = name;        }        public int getAge() {                return age;        }        public void setAge(int age) {                this.age = age;        }}

4.业务层接口与实现类

业务层接口

package com.gql.service;import java.util.List;import com.gql.entity.User;/** * 类说明: *         业务层接口 * @guoqianliang1998. */public interface UserService {        void save(User user);        void update(int id, User user);        void delete(int id);        User getUser(int id);        List getUserList(int[] ids);                List getUserList();}

业务层实现类

package com.gql.service;import java.util.List;import com.gql.dao.UserDao;import com.gql.entity.User;/** * 类说明: *         业务层实现类 * @guoqianliang1998. */public class UserServiceImp implements UserService {        private UserDao userDao;                public void setUserDao(UserDao userDao) {                this.userDao = userDao;        }        @Override        public void save(User user) {                userDao.save(user);                int i = 1/0;        }        @Override        public void update(int id, User user) {                userDao.update(id, user);        }        @Override        public void delete(int id) {                userDao.delete(id);        }        @Override        public User getUser(int id) {                User user = userDao.getUser(id);                return user;        }        @Override        public List getUserList(int[] ids) {                List userList = userDao.getUserList(ids);                return userList;        }        @Override        public List getUserList() {                List list = userDao.getUserList();                return list;        }}

5.数据访问层接口与实现类

数据访问层接口

package com.gql.dao;import java.util.List;import com.gql.entity.User;/** * 类说明:  *            数据访问层接口  * @guoqianliang1998. */public interface UserDao {        void save(User user);        void update(int id, User user);        void delete(int id);        User getUser(int id);        List getUserList(int[] ids);                List getUserList();    }

数据访问层实现类

package com.gql.dao;import java.sql.ResultSet;import java.sql.SQLException;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.jdbc.core.RowMapper;import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;import com.gql.RowMapper.UserRowMapper;import com.gql.entity.User;/** * 类说明:  *            数据访问层实现类  * @guoqianliang1998. */public class UserDaoImp implements UserDao {        private JdbcTemplate jdbcTemplate;        public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {                this.jdbcTemplate = jdbcTemplate;        }        @Override        public void save(User user) {                String sql = "INSERT INTO user values(NULL,?,?)";                jdbcTemplate.update(sql, user.getName(), user.getAge());        }        @Override        public void update(int id, User user) {                String sql = "update user set name=?,age=? WHERE id = ?";                jdbcTemplate.update(sql, user.getName(), user.getAge(), id);        }        @Override        public void delete(int id) {                String sql = "DELETE FROM user WHERE id = ?;";                jdbcTemplate.update(sql, id);        }        @Override        public User getUser(int id) {                String sql = "select * from user where id = ?";                User user = jdbcTemplate.queryForObject(sql, new RowMapper() {                        @Override                        public User mapRow(ResultSet rs, int rowNum) throws SQLException {                                User user = new User();                                user.setId(rs.getInt(1));                                user.setName(rs.getString(2));                                user.setAge(rs.getInt(3));                                return user;                        }                }, id);                return user;        }        @Override        public List getUserList(int[] ids) {                String sql = "select * from user where id in(:ids)";                                NamedParameterJdbcTemplate n = new NamedParameterJdbcTemplate(jdbcTemplate.getDataSource());                Map paramMap = new HashMap();                List list = new ArrayList();                for (int i = 0; i < ids.length; i++) {                        list.add(ids[i]);                }                paramMap.put("ids", list);                List userList = n.query(sql, paramMap, new RowMapper(){                        @Override                        public User mapRow(ResultSet rs, int rowNum) throws SQLException {                                User user = new User();                                user.setId(rs.getInt(1));                                user.setName(rs.getString(2));                                user.setAge(rs.getInt(3));                                return user;                        }                });                return userList;                //              第二种写法↓↓↓//              StringBuilder sb = new StringBuilder();//              sb.append("SELECT * FROM user WHERE id = ?");//              for(int i=0;i userList = jdbcTemplate.query(sb.toString(),args,new RowMapper() {//                      //                      @Override//                      public Object mapRow(ResultSet rs, int rowNum) throws SQLException {//                              User user = new User();//                              user.setId(rs.getInt(1));//                              user.setName(rs.getString(2));//                              user.setAge(rs.getInt(3));//                              return user;//                      }       //              });//              return userList;        }        @Override        public List getUserList() {                String sql = "select * from user";                List list = jdbcTemplate.query(sql, new UserRowMapper());                return list;        }}

6.配置c3p0数据源/业务层/数据访问层

配置c3p0数据源

业务层

数据访问层

7.配置事务管理器

8.配置事务的通知

事务的通知：

• 配置事务的通知来引用事务管理器

• 告诉Spring容器采用哪种事务管理机制.

• 告诉Spring容器目标方法采用什么样的事务处理策略.

通知内配置事务的属性

9.配置 AOP 切入点表达式

10.配置切入点表达式和事务通知的对应关系
