SqlMapClientFactoryBean相关问题

新搭了一个项目在测试时报了一个错误：

com.ibatis.sqlmap.client.SqlMapException: There is no statement named findUserByMap in this SqlMap.
	at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.getMappedStatement(SqlMapExecutorDelegate.java:231)
	at com.ibatis.sqlmap.engine.impl.SqlMapClientImpl.getMappedStatement(SqlMapClientImpl.java:201)

根据错误定位到代码是发生在下面的方法中：

public MappedStatement getMappedStatement(String id)
/*     */   {
/* 229 */     MappedStatement ms = (MappedStatement)this.mappedStatements.get(id);
/* 230 */     if (ms == null) {
/* 231 */       throw new SqlMapException("There is no statement named " + id + " in this SqlMap.");
/*     */     }
/* 233 */     return ms;
/*     */   }

说明mappedStatements.get(id)调用结果为空，说明查询调的sql配置的xml中语句id未空，也就是说没有ibatis没有加载我的配置文件，这么一来问题就很明显了，是我的ibatis配置有问题。ibatis配置如下：

这才发现，配置ibatis时只配置了扫描一个xml，这里需要加上扫描通配符匹配到的目录下的xml。另外测试发现必须要配置一个configLocation，否则会报错，现在ibatis配置如下：

重启报错如下：

2018-05-31 19:35:10,250 WARN [org.springframework.web.context.support.XmlWebApplicationContext] - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'testsqlaction': Unsatisfied dependency expressed through field 'testSqlService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testSqlService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'testSqlDao': Unsatisfied dependency expressed through field 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring/spring-mybatis.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'mapperLocations' of bean class [org.springframework.orm.ibatis.SqlMapClientFactoryBean]: Bean property 'mapperLocations' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

从报错可以看出是ibatis配置无法识别属性mapperLocaltions，查看SqlMapClientFactoryBean的源码发现，ibatis映射xml是使用的mappingLocations：

/**
     * Set locations of iBATIS sql-map mapping files that are going to be
     * merged into the SqlMapClient configuration at runtime.
     * 
This is an alternative to specifying "" entries
     * in a sql-map-client config file. This property being based on Spring's
     * resource abstraction also allows for specifying resource patterns here:
     * e.g. "/myApp/*-map.xml".
     * 
Note that this feature requires iBATIS 2.3.2; it will not work
     * with any previous iBATIS version.
     */
    public void setMappingLocations(Resource[] mappingLocations)
    {
        this.mappingLocations = mappingLocations;
    }

并且从源码注释也可以看出是从2.3.2版本开始生效，之前版本是无效的。这就和MyBatis有点区别了，Mybatis配置如下：

Mybatis使用的才是mapperLocations。
