Oracle和MySQL数据库的批量update在mybatis中配置不太一样:
oracle数据库:

<code class = "hljs tcl" style= "" ><<span class = "hljs-keyword" style= "" >update</span> id=<span class = "hljs-string" style= "" > "batchUpdate" </span> parameterType=<span class = "hljs-string" style= "" > "java.util.List" </span>>
<<span class = "hljs-keyword" style= "" >foreach</span> collection=<span class = "hljs-string" style= "" > "list" </span> item=<span class = "hljs-string" style= "" > "item" </span> index=<span class = "hljs-string" style= "" > "index" </span> <span class = "hljs-keyword" style= "" >open</span>=<span class = "hljs-string" style= "" > "begin" </span> <span class = "hljs-keyword" style= "" >close</span>=<span class = "hljs-string" style= "" > "end;" </span> separator=<span class = "hljs-string" style= "" > ";" </span>>
<span class = "hljs-keyword" style= "" >update</span> test
<<span class = "hljs-keyword" style= "" >set</span>>
test=${item.test}+<span class = "hljs-number" style= "" > 1 </span>
</<span class = "hljs-keyword" style= "" >set</span>>
where id = ${item.id}
</<span class = "hljs-keyword" style= "" >foreach</span>>
</<span class = "hljs-keyword" style= "" >update</span>></code>

mysql数据库:
mysql数据库采用一下写法即可执行,但是数据库连接必须配置:&allowMultiQueries=true
例如:jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
