Spring Rest路径与@PathVariable和@MatrixVariable

Question

我使用的是Spring4.1.9.版本

配置下一个Rest控制器。

并创建了/get/{id}以某种方式隐藏/get/matrix/{vars}的映射

当我尝试通过下一个url调用它时http://localhost:8080/testmatrixvariables/get/matrix/；v1=1；v2=2；v3=3我从调试日志中获得

org.html" target="_blank">springframework.beans.TypeMisMatchException：无法将类型[java.lang.String]的值转换为所需的类型[long]；嵌套异常是java.lang.NumberFormatException：对于输入字符串：“Matrix”

似乎是尝试从我的url解析{id}，但不是/get/matrix/{vars}

在同一时间下一次调用完全工作http：//localhost:8080/testmatrixvariables/getmatrix/；v1=1；v2=2；v3=3和http：//localhost:8080/testmatrixvariables/get/1同样工作良好，http：//localhost:8080/testmatrixvariables/get/anotherpathvariable/2同样工作

所以只有当@pathvariable和@matrixvariable之间存在冲突时才会出现问题

http://localhost:8080/testmatrixvariables/get/matrix/；v1=1；v2=2；v3=3

@RestController
@RequestMapping(value = "/testMatrixVariables")
public class TestController {

    @RequestMapping(value = "/get/{id}", method = RequestMethod.GET)
    public
    @ResponseBody
    ResponseEntity<String> getByPathVariable(@PathVariable("id") long v1) {
        return ResponseEntity.ok("ok" + v1);
    }

    @RequestMapping(value = "/get/anotherPathVariable/{id}", method = RequestMethod.GET)
    public
    @ResponseBody
    ResponseEntity<String> getAnotherPathVariableByPathVariable(@PathVariable("id") long v1) {
        return ResponseEntity.ok("ok" + v1);
    }


    @RequestMapping(value = "/getMatrix/{vars}", method = RequestMethod.GET)
    public @ResponseBody ResponseEntity<String> getMatrix(
            @MatrixVariable(pathVar = "vars", required = true) String v1,
            @MatrixVariable(pathVar = "vars", required = true) String v2,
            @MatrixVariable(pathVar = "vars", required = true) String v3) {
        return ResponseEntity.ok("ok" + v1 + v2 + v3);
    }

    @RequestMapping(value = "/get/matrix/{vars}", method = RequestMethod.GET)
    public @ResponseBody ResponseEntity<String> getGetMatrix(
            @MatrixVariable(pathVar = "vars", required = true) String v1,
            @MatrixVariable(pathVar = "vars", required = true) String v2,
            @MatrixVariable(pathVar = "vars", required = true) String v3) {
        return ResponseEntity.ok("ok" + v1 + v2 + v3);
    }

}

这不起作用，因为默认情况下禁用了矩阵变量。可以通过两种方式启用它：

将RequestMappingHandlerMapping的removeSemicolonContent属性设置为false。默认情况下，它被设置为true。例如：Handler.SetRemoveSemicolonContent（false）；

或者如果您使用的是xml配置,则可以按照

<mvc:annotation-driven enable-matrix-variables="true"/>
