狂神说Mybatis向数据库插入数据时中文显示？问题

先放源代码：

 1     @org.junit.Test
 2     public void addInitBlog(){
 3         SqlSession session = MybatisUtils.getSqlSession();
 4         BlogMapper mapper = session.getMapper(BlogMapper.class);
 5         Blog blog = new Blog();
 6         blog.setId(IDUtils.getID());
 7         blog.setTitle("Mybatis如此简单");
 8         blog.setAuthor("狂神说");
 9         blog.setCreateTime(new Date());
10         blog.setViews(9999);
11         mapper.addBlog(blog);
12         blog.setId(IDUtils.getID());
13         blog.setTitle("Java如此简单");
14         mapper.addBlog(blog);
15         blog.setId(IDUtils.getID());
16         blog.setTitle("Spring如此简单");
17         mapper.addBlog(blog);
18         blog.setId(IDUtils.getID());
19         blog.setTitle("微服务如此简单");
20         mapper.addBlog(blog);
21         session.close();
22     }
