报错：org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

springboot2配置mybatis-plus后调用BaseMapper方法插入数据时报错：
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

jar包：

<!-- mybatis增强工具 -->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.1.2</version>

最终发现是配置的DataSource文件导致：

        }
        if (maxWait != null) {
            datasource.setMaxWait(maxWait);
        }
        if (timeBetweenEvictionRunsMillis != null) {
            datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);

        if (minEvictableIdleTimeMillis != null) {

        }
        if (testOnReturn != null) {
            datasource.setTestOnReturn(testOnReturn);
        }
        if (poolPreparedStatements != null) {
            datasource.setPoolPreparedStatements(poolPreparedStatements);
        }
        if (maxPoolPreparedStatementPerConnectionSize != null) {
            datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);
        }

        if (connectionProperties != null) {
            datasource.setConnectionProperties(connectionProperties);
        }

        List<Filter> filters = new ArrayList<>();
        filters.add(statFilter());
        filters.add(wallFilter());
        datasource.setProxyFilters(filters);

        //druid数据库密码加密
        try {
            datasource.setFilters("config"); //数据库过滤器
        } catch (SQLException e) {
            e.printStackTrace();
        }
        Properties properties = new Properties();
        properties.setProperty("config.decrypt","true"); //加密
        datasource.setConnectProperties(properties);

        return datasource;
    }

    @Bean(name = "statFilter")
    @Primary
    public StatFilter statFilter() {
        StatFilter statFilter = new StatFilter();
        statFilter.setLogSlowSql(true);
        statFilter.setMergeSql(true);
        statFilter.setSlowSqlMillis(1000);

        return statFilter;
    }

    @Bean(name = "wallFilter")
    @Primary
    public WallFilter wallFilter() {
        WallFilter wallFilter = new WallFilter();

        // 允许执行多条SQL
        WallConfig config = new WallConfig();
        config.setMultiStatementAllow(true);
        wallFilter.setConfig(config);

        return wallFilter;
    }

    @Bean(name = "jdbcTemplate")
    @Primary
    public JdbcTemplate jdbcTemplate() {
        return new JdbcTemplate(dataSource());
    }

    @Bean(name = "transactionManager")
    @Primary
    public DataSourceTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }

    @Bean(name = "sqlSessionFactory")
    @Primary
    public SqlSessionFactory setSqlSessionFactory(@Qualifier("dataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mapper/*.xml"));
        return bean.getObject();
    }

    @Bean(name = "sqlSessionTemplate")
    @Primary
    public SqlSessionTemplate setSqlSessionTemplate(@Qualifier("sqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    public String getDbUrl() {
        return dbUrl;
    }

}

注释掉sqlSessionFactory和sqlSessionTemplate两个Bean就可以正常调用mybatis-plus的方法了。因为有这两段代码它就不能调用MybatisSqlSessionFactoryBean，也就无法绑定Mybatis-plus的方法。

最终我把文件全部注释了，使application.yml中配置的dataSource

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/hune?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true&useSSL=false

      max-active: 100
      #获取连接时最大等待时间，单位毫秒

      #用来检测连接是否有效的sql 必须是一个查询语句
      #mysql中为 select 'x'
      #oracle中为 select 1 from dual
      validation-query: select 'x'
      #申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效。
      test-while-idle: true

      connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000;config.decrypt=true;
      #合并多个DruidDataSource的监控数据
      use-global-data-source-stat: true
      #设置访问druid监控页的账号和密码,默认没有 http://localhost:9000/hune/druid/index.html
      stat-view-servlet:
        login-username: admin
        login-password: admin

最终测试mybatis-plus的方法成功插入数据。
