通过DataSourceTransactionManager实现Spring事务

通过注解实现

在需要使用事务的方法上添加"@Transactional"，注解，可以通过"rollbackFor"指定特定异常时才进行回滚操作

@Transactional(rollbackFor = Exception.class)
@Override
public void addPermission(String roleName, Set permissions) throws SQLException{
    String addPermission = "INSERT  INTO shiro_web_roles_permissions (role,permission) VALUES (?,?)";
    //批量添加数据
    jdbcTemplate.batchUpdate(addPermission, new BatchPreparedStatementSetter() {
        @Override
        public void setValues(PreparedStatement ps, int i) throws SQLException {
            ps.setString(1, roleName);
            ps.setString(2, tempPermissions.get(i));
        }


        @Override
        public int getBatchSize() {
            return permissions.size();
        }
    });
}

通过AOP配置全局事务

使用该种方法，可以不用手动添加"@Transactional"注解
maven依赖:

    org.aspectj
    aspectjrt
    1.6.12


    org.aspectj
    aspectjweaver
    1.6.12

编程式事务

需要手动commit以及rollback，比以上各种方式更灵活

public void addPermission(String roleName, Set permissions) throws SQLException{
    String addPermission = "INSERT  INTO shiro_web_roles_permissions (role,permission) VALUES (?,?)";
    //声明TransactionDefinition
    DefaultTransactionDefinition transactionDefinition = new DefaultTransactionDefinition();
    //声明DatasourceTransactionManager
    DataSourceTransactionManager dm = new DataSourceTransactionManager(jdbcTemplate.getDataSource());
    //声明TransactionStatus
    TransactionStatus tmp = dm.getTransaction(transactionDefinition);
    permissions.remove("");
    ArrayList tempPermissions = new ArrayList<>(permissions);
    try {
        //批量添加数据
        jdbcTemplate.batchUpdate(addPermission, new BatchPreparedStatementSetter() {
            @Override
            public void setValues(PreparedStatement ps, int i) throws SQLException {
                ps.setString(1, roleName);
                ps.setString(2, tempPermissions.get(i));
            }
            
            @Override
            public int getBatchSize() {
                return permissions.size();
            }
        });
        //手动提交事务
        dm.commit(tmp);
    }catch (Exception e){
        //发生异常时回滚
        dm.rollback(tmp);
        //把异常抛出，让调用方处理
        throw e;
    }
}
