我想向sum(time_entries.hours)sql select 添加新列我正在查询这样的条目:
issues = Issue.visible.where(options[:conditions]).all(
:include => ([:status, :project, :time_entries] + (options[:include] || [])).uniq,
:conditions => statement,
:order => order_option,
:joins => query_joins(order_option.join(',')),
:limit => options[:limit],
:offset => options[:offset],
:group => "#{Issue.table_name}.id"
)
它生成这个选择:
SELECT
"issues"."id" AS t0_r0,
...
"time_entries"."hours" AS t3_r4,
...
"versions"."sharing" AS t8_r9
FROM "issues"
LEFT OUTER JOIN "projects" ON "projects"."id" = "issues"."project_id"
LEFT OUTER JOIN "issue_statuses" ON "issue_statuses"."id" = "issues"."status_id"
LEFT OUTER JOIN "time_entries" ON "time_entries"."issue_id" = "issues"."id"
LEFT OUTER JOIN "users" ON …我这样使用混淆器：
<proguard configuration="${proguard.config}" ignorewarnings="true">
<libraryjar dir="${build.lib}" filter="!some**.jar"/>
<injar file="${build.dir.result}/some.jar"/>
<injar>
<fileset refid="another.jars"/>
</injar>
<outjar file="${build.dir.result}/some_obf.jar"/>
<keep name="${entrypoint.class}">
<method name="main"/>
</keep>
</proguard>
在配置中我还有选项（以及更多 -keep）：
-adaptresourcefilenames **.properties
-adaptresourcefilecontents
在 jar 中，我编译了类和 spring xml 配置。配置位于 META-INF/spring/ 中。所有类名称均被正常混淆（选中），来自 xml 的所有类均被混淆并具有新名称。我想用混淆的类名替换 spring xml 中的完全限定类名。这就是为什么我添加了 adaptresourcefilecontents 参数，但 xml 未受影响。怎么了？
